Alexanian, Garnik (Montreal): On
D-brane topology change
A study of the relation between topology change, energy and
Lie algebra representations for fuzzy geometry in connection to M-theory is
presented. We encounter two different types of topology change, related to
the different features of the Lie algebra representations appearing in the
matrix models of M-theory. From these studies, we propose a new method of
obtaining non-commutative solutions for the non-Abelian D-brane action found
by Myers. This mechanism excludes one of the two topology changing processes
previously found in other non-commutative solutions of many matrix-based models
in M-theory i.e. in M(atrix) theory, Matrix string theory and non-Abelian
D-brane physics.

Barron,
Katrina (Notre Dame): The worldsheet supergeometry
of superconformal field theory
Propagating superstrings sweep out a worldsheet in space-time
that is a super-Riemann surface. This worldsheet supergeometry will be used
to study the vertex operator superalgebras of correlation functions corresponding
to propagating superstrings. For instance change of variables formulas for
vertex operator superalgebras will be derived and symmetries corresponding
to different choices of superconformal operator on the worldsheet will be
studied.

Berger,
Mike (Indiana): Superfield realizations
of Lorentz violation
Superfield realizations of Lorentz-violating extensions of
the Wess-Zumino model are presented. These models retain supersymmetry but
include terms that explicitly break the Lorentz symmetry. The models can be
understood as arising from superspace transformations that are modifications.
Bergman,
Oren (Technion): Quantum Hall physics in
string theory
In certain backgrounds string theory exhibits quantum Hall-like
behavior. These backgrounds provide an explicit realization of the effective
non-commutative gauge theory description of the fractional quantum Hall effect
(FQHE), and of the corresponding large N matrix model. This suggests a new
role for string theory as an effective theory of the FQHE.

Besprosvany,
Jaime (UNAM): Standard-model coupling constants
from compositeness: quantum mechanics and symmetry arguments
A coupling-constant definition is given based on the compositeness
property of some particle states with respect to the elementary states of
other particles. It is applied in the context of the vector-spin-1/2-particle
interaction vertices of a field theory, and the standard model. The definition
reproduces Weinberg's angle in a grand-unified theory. One obtains coupling
values close to the experimental ones for appropriate configurations of the
standard-model vector particles, at the unification scale within grand-unified
models, and at the electroweak breaking scale. The use of quantum mechanics
and symmetry arguments is emphasized.
Bohm,
Arno (Austin): Theoretical framework for
relativistic resonances
Breit-Wigner lineshape and exponential decay have been the
two signatures of quasistable states. In non-relativistic physics they are
related by a unified theory that predicts the lifetime-width relation as an
exact equality. For relativistic resonances one does not have a generally
accepted lineshape formula. Further choosing the relativistic Breit-Wigner
lineshape does not uniquely define the mass and width of a resonance. For
these reasons the Particle Data Table gives several different values for mass
and width of some well measured reasonances. We shall show that the transformation
property of Relativistic Gamow vectors under Poincare transformations lead
to a unique definition of mass and width.

There are hints from string theory that nature might

irreducible representations of conformal supersymmetry

the exceptional irreps.

Michael (Michigan):Hidden
space-time symmetries in M-theory
In M-theory vacua with vanishing 4-form P, one can invoke the
ordinary Riemannian holonomy H/subset SO(1,10) to account for unbroken supersymmetries
n=1,2,3,4,6,8,16,32. However, the generalized holonomy conjecture, valid for
non-zero P, can account for more exotic fractions of supersymmetry, in particular
16 <n<32. The conjectured holonomies are given by H/subset G where G
are the generalized structure groups. These involve previously unidentified
hidden spacetime symmetries of the theory.
Dunne,
Gerald (Connecticut): Self-duality, helicity
and higher-loop Euler-Heisenberg effective actions
A number of dramatic simplifications have recently been found
in the computation of higher-loop QED effective actions with background fields
of definite helicity. The physical origin of these simplifications lies in
a deep relation between helicity, self-duality and supersymmetry. Applications
include higher-loop effective actions, pair production formulas, helicity
amplitudes and beta functions.

Freund,
Peter (Chicago): Physics and geometry
In the Physics of Galilei and Newton arbitrary matter moves
in a Galilean invariant manner under the influence of arbitrary forces
in a commutative Euclidean 3-dimensional space and an absolute 1-dimensional
time. In String Theory the forms of matter and the forces are unified and
as such are no longer arbitrary. This unification also constrains the geometry
of space-time, which is higher-dimensional, non-euclidean and in general noncommutative.
The very dimensionality of space becomes relative: it depends on which description
is choosen from a pair of dual descriptions.
Fukuma,
Masafumi (Kyoto): Effects of space-time
noncommutativity on the angular power spectrum of the CMB
We investigate an inflationary model of the universe based
on the assumption that space-time is noncommutativity in the very early universe.
We analyze the effects of space-time noncommurarivity on the quantum fluctuations
of an inflation and investigate their contributions to the cosmic microwave
background (CMB). We show that the angular power spectrum (l+1)C_l generally
has a sharp damping for l if we assume that the last scattering surfaceis
traced back to fuzzy spheres at the times when large-scale modes cross the
Hubble horizon. (hep-th/0307029)

Greenberg,
Oscar (Maryland): Why is CPT fundamental?
The CPT theorem was proved almost half a century ago from the
point of view of Lagrangian quantum field theory. A more general proof based
on "axolatic " field theory was given nearly as long ago. The axiomatic
point of view has two advantages over the Lagrangian one. First, the axiomatic
point of view makes clear why CPT is fundamental-because it is intimately
related to Lorentz invariance. Secondly, the axiomatic proof gives a simple
way to calculate the CPT transform of any relativistic field without calculating
C, P and T separately and then multiplying them. The purpose of this pedagogical
talk is to "deaxiomatize" the CPT theorem by explaining it in a
few simple steps.
Guendelman,
Eduardo (Ben Gurion): Scale symmetry breaking
from the dynamics of maximal rank gauge fields
Scale invariant theories which contain maximal rank gauge field
strengths (of D indices in D dimensions) are studied. The integration of the
equations of motion of these gauge fields leads to the s.s.b. of scale invariance.
We study examples in particle mechanics, mass generation in field theory,
the generation of non trivial dilaton potentials in generally covariant theories
and the spontaneous generation of confining behavior in gauge theories.

Vladislav (UNAM): Quantum Lie operations
and differential calculi.
The notion of quantum Lie operation naturally appeared in line
with the Friedrichs criteria for Lie polynomials. This notion generalizes
and unites colored super-brackets, Pareigis multilinear quantum Lie operations,
and quantum Serre operations. The author has found the necessary and sufficient
condition for a multilinear quantum operation to exist (Journal of Algebra,
217, 188-228, 1999). We prove that the $(n-2)!$-dimensional space of
generic quantum Lie operations has a basis of the symmetric operations. In
the general case almost always a basis of symmetric operations exists. All
exceptional cases are found. We propose a notion of a quantum universal enveloping
algebra based on the quantum Lie operation concept. This enveloping algebra
has PBW basis that admit a deformation by means of the Kashiwara crystallization
idea. Every homogeneous bigraded braided Hopf algebra over a field of zero
characteristic is a Q-universal enveloping algebra of a suitable Lie algebra.
We apply the noncommutative differential calculi methods to investigate the
quantum operations and more generally the braided Hopf algebras generated
by primitive elements. It is shown that every differential ideal in any differential
algebra with coordinate calculus set up by a Yang-Baxter operator (not necessary
invertible) is generated by constants.
Kosower,
David (Saclay): Peeking at all orders in
N=4 SUSY
The Maldacena conjecture suggests that N=4 gauge theories in
the planar ('t Hooft) limit have a special simplicity in the structure of
their perturbative expansions. We demonstrate explicitly that such a simple
relation exists between two-loop and one-loop four-point amplitudes. An analogous
relationship is expected to hold for n-point amplitudes. Several arguments
suggest that a similar structure should continue to all loop orders.
Leblond,
Louis (Cornell): Dp-D(p-2) dynamics and
possible applications to cosmology
I will present some interesting results regarding the dynamics
of the Dp-D(p-2) system. We now have two different ways to get an approximate
Dp-D(p-2) action from boundary string field theory: as a particular vortex
solution of 2 D-branes and 1 anti-D-brane and as the T-dual of branes at right
angle. I will justify where our action comes from and then apply it to study
the dynamics of the dissolution process of the D(p-2) into the Dp. I will
then comment on the possible application to inflation and reheating.

Luca (INFN): Canonical reduction of gravity:
from general covariance to Dirac observables and post-Minkowskian background-independent
gravitational waves.
A Shanmugadhasan canonical transformation adapted to 13 of
the 14 first class constraints of tetrad gravity allows to identify the Dirac
observables of the gravitational field in spacetimes of the Christodoulou-Klainermann
type. A background-independent Hamiltonian linearization is then defined in
a completely fixed non-harmonic 3-orthogonal gauge, all the linearized constraints
are solved and the gravitational waves in post-Minkowskian spacetimes are
found. With perfect fluids the post-Minkowskian quadrupole emission formula,
resummation of the post-Newtonian approximations, is obtained. Finally some
comments are made on the existence of simultaneous Dirac and Bergmann observables
and on their rolein a new quantization program for gravity.

Samir (Ohio State): Where are the states
of a black hole?
We show that the 2-charge extremal system has a complete set
of 'hair', i.e. there are different geometries corresponding to different
quantum states of the system, and the number of these states gives the Bekenstein
entropy. The area entropy is recovered by 'coarse graining over the 'hair'.
We then work toward extending this construction to the 3-charge system, which
has all the properties of a classical black hole.
Michelson,
Jeremy (Kentucky): Matrix string theory
of pp waves
Matrix Theory is an area for exploring nonperturbative string
theory and M-theory. I will discuss properties of Matrix and Martrix String
Theory for ppWave backgrounds. Particular emphasis will be put on the existence
of nontrivial supersymmetic solutions of the Matrix theory and resulting properties
of the theory.
Minic,
Djordje (Virginia Tech): Time, quantum
mechanics and holography
We argue that the demand of background independence in a quantum
theory of gravity calls for an extension of standard geometric quantum mechanics.
We discuss a possible kinematical and dynamical generalization of the latter
by way of a quantum covariance of the state space. Specifically, we apply
our scheme to the problem of a background independent formulation of Matrix
Theory.
Moylan,
Patrick (Penn State): Representations of
the Poincare group from positive energy representations for SO(2,3)
We explore the possibility of constructing unitary representations
of the Poincare group on representation spaces for positive energy representations
of SO(2,3). The Poincare representations which we construct are obtained from
results of ours on embeddings of Poincare Lie algebras into skew field extensions
of the enveloping algebras of the de Sitter and anti deSitter groups. We review
these results and also discuss similar results which we have obtained for
q-deformations Uq(so(m,n)) with small m and n values. We apply these results
to construct skew-symmetric representations of the Poincare Lie algebra on
unitary irreducible representation spaces of SOo(2,3)~, the universal cover
of the anti-de Sitter group. Detailed and explicit results are given for some
particular representations of SOo(2,3)~ which extend to massless, unitary
irreducible representations of SU(2,2), the four-fold cover of the conformal
group of Minkowski space-time. Our results have applications to the problem
of localizability of massless particles.

Nitta,
Muneto (Perdue): BPS domain walls in massive
hyper-Kahler sigma models
The Higgs branch of N=2 supersymmetric gauge theories with
non-Abelian gauge groups are described by hyper-Kahler (HK) nonlinear sigma
models with potential terms. With the non-Abelian HK quotient by U(M) and
SU(M) gauge groups, we give the massive HK sigma models that are not toric.
The U(M)quotient gives N!/(M! (N-M)!) discrete vacua that may allow various
types of domain walls, whereas the SU(M) quotient gives only trivial vacuum.
We then construct the BPS domain wall solution in the case of the simplest
model, the massive Eguchi-Hanson model.

Sarada (Rochester): Simplicial gauge theory:
an approach to studying the mass gap of 2+1 Yang-Mills theory
We propose a modification of the lattice regularization of
gauge theories, allowing for arbitrary triangulations instead of just regular
lattices. This allows us to take advantage of symmetries that change the metric
of space (such as conformal and area preserving diffeomorphisms) even within
the discrete version of the theory. It is hoped that this approach will eventually
give a mathematically rigorous construction of 2+1 dimensional gauge theory.
In our approach gauge invariance and the discrete version of space-time symmetries
are manifest. We complement and confirm the remarkable results of Karabali,
Nair and others on 2+1 Yang--Mills theory, obtained in the holomorphic gauge.

Mohammad (Stanford): A review on plane-wave/SYM
duality
According to the usual AdS/CFT duality, type IIB string theory
on AdS_5xS^5 background is dual to N=4, D=4 superconformal gauge theory. This
duality, however, is a strong/weak duality, in the sense that when the 't
Hooft coupling of the gauge theory is large two dimensional worldsheet theory
is weakly coupled and vice-versa. Recently it has been proposed that the above
duality restricted to the large R-charge sector of the gauge theory side,
leads to another duality, Plane-wave/SYM duality, according which type IIB
string theory on (the maximally supersymmetric) plane-wave background is dual
to the large R-charge secotr of N=4, D=4 gauge theory, the so-called BMN sector.
The main advantage of this duality is that it provides us with a regime where
both of the string theory and guage theory are perturbative. This duality
has been in the main line of research work in string theory in the last one
a half year. In this talk I will state the duality and and some of the supporting
evidence and the new insight resulting from that to the whole string theory/gauge
theory duality.

Kazunari (Saitama IT): Nonlinear supersymmetric
Einstein-Hilbert-type action and unity of nature
A nonlinear supersymmetric(NLSUSY) Einstein-Hilbert-type action
is obtained by the Einstein gravity analogue geomtrical arguments in high
symmetry spacetime inspired by NLSUSY, where besides the Minkowski coordinate
x^a the coset space coordinates \psi of superGL(4,R)/GL(4,R) turning to the
Nambu-Goldstone(NG) fermion degrees of freedom (d.o.f.) are attached at every
spacetime point. A new mechanism which converts spacetime d.o.f into the dynamical
d.o.f isproposed besides the Kaluza-Klein mechanism. All elementary particles
except the graviton are composed of NG fermion "superon" of NLSUSY
and regarded as the eigenstates of SO(10) super-Poincare algebra (superon-graviton
model of nature). Implications of super-graviton model for the low energy
particle physics and the cosmology are discussed. The linearization of NLSUSY
and N=1 SGM action is performed explicitly to obtain an equivalent renoemalizable
local field theory.

For simplicity, we try to find the solution of the Dirac equation as a template
of the gauge field theory. We will show how to obtain the solution of the
Dirac equation with the interaction term. And the results can be applied to
general gauge field theory. This is a great achievement of the gauge field
theory.

part of the triangle is not renormalized in the chiral limit. We derive a
new nonrenormalization theorem for the transversal part of the triangle. This
nonrenormalization, in difference with the longitudinal part, holds on only

String topology was introduced a few years ago by M. Chas and

on the homology of the free loop space in a compact manifold. This structure
describes interaction of strings (loops) in the manifold and mimics the Gromov-Witten
invariants in a purely topological setting. I will discuss string topology,
as well as brane topology, a higher-dimensional generalization of string topology,
where strings get replaced by spheres. This generalization is related to Hochschild
cohomology and a conjecture of Kontsevich. Some of this is joint work with
Dennis Sullivan.

James T. (Utah State): Biconformal supergravity
Although research in the '70s exhausted most possibilities
for conformal supergravity, one consistent superconformal gauging has remained
unexplored. In this remaining theory, we use the group manifold method to
extend spacetime to an 8-dim bosonic symplectic manifold, together with either
8 or 16 additional fermionic coordinates. For the 24-dim superspace, the volume
form is dimensionless and we write an 11 parameter class of invariant actions
linear in the curvatures. These linear actions descend to general relativity
in the bosonic sector and a Rarita-Schwinger type equation for the spin 3/2
field. In addition there is an SU(N) internal symmetry.

into difference ones and coordinates into certain operators, while preserving
the Heisenberg relations between them.
