Chiral Symmetry Breaking by a Magnetic Field in Weak-coupling QED
C. N. Leung, Y. J. Ng, A. W. Ackley
Using the nonperturbative Schwinger-Dyson equation, we show that chiral symmetry in weak-coupling massless QED is dynamically broken by a constant but arbitrarily strong external m…
Picard group of the moduli spaces of G-bundles
Shrawan Kumar, M. S. Narasimhan
We prove that the Picard group of the moduli space of semistable G-bundles on any irreducible smooth projective curve is isomorphic with the group of integers.
The Post-Merger Elliptical NGC 1700: Stellar Kinematic Fields to Four Effective Radii
Thomas S. Statler, Tammy Smecker-Hane, Gerald N. Cecil
We have measured the stellar motions in the elliptical galaxy NGC 1700 along four position angles, to very large radii, using absorption features in spectra obtained with the Multi…
Kadell's two conjectures for Macdonald polynomials
Ivan Cherednik
This paper contains the proof of difference counterparts of the conjectures due to Keven Kadell on symmetric and anti-symmetric Macdonald polynomials.
Limit on T-Violating P-Conserving Interaction from the Decay of Fe
M. T. Ressell, J. Engel, P. Vogel
We use the experimental limit on the interference of M1 and E2 multipoles in the -decay of Fe to bound the time-reversal-violating parity-conserving vertex. Our ap…
Constraining from the Hidden Sector
Paul H. Frampton, Bettina Keszthelyi, Brian D. Wright +1
By including the effects of superstring thresholds, we reconsider minimal string unification together with the requirement of producing a supersymmetry-breaking gluino condensate i…
An Extended N=1 Fermionic Supercurrent and its Associated N=2 Superconformal Algebra
David M. Pierce
An extended free fermionic construction of the internal N=1 world sheet supercurrent for four-dimensional superstring theory is given. We show how it can describe theories with mas…
New Aspects of Reheating
D. Boyanovsky, M. D'attanasio, H. J. de Vega +2
The reheating stage in post-inflationary cosmologies is reanalyzed. New techniques from non-equilibrium quantum field theory allow a consistent derivation of the equation of motion…
Dicyclic Horizontal Symmetry and Supersymmetric Grand Unification
Paul H. Frampton, Otto C. W. Kong
It is shown how to use as horizontal symmetry the dicyclic group in a supersymmetric unification where one acts on the…
Flavors and Horizontal Symmetries
Paul H. Frampton
After a brief introduction to what are the basic flavor questions to be addressed, I introduce the underlying ideas of horizontal symmetries, with group . For the purposes of…
The (0,2) Exactly Solvable Structure of Chiral Rings, Landau-Ginzburg Theories and Calabi-Yau Manifolds
Ralph Blumenhagen, Rolf Schimmrigk, Andreas Wisskirchen
We identify the exactly solvable theory of the conformal fixed point of (0,2) Calabi-Yau sigma-models and their Landau-Ginzburg phases. To this end we consider a number of (0,2) mo…
Infinite Grassmannians and Moduli Spaces of G-bundles
Shrawan Kumar
This lecture note is devoted to prove that the space of vacua is isomorphic with the space of generalized theta functions (joint work with M.S. Narasimhan, and A. Ramanathan)
Thermodynamics of an Anyon System
Wei Chen
We examine the thermal behavior of a relativistic anyon system, dynamically realized by coupling a charged massive spin-1 field to a Chern-Simons gauge field. We calculate the free…
Structure of Pairs in Heavy Weakly-Bound Nuclei
J. R. Bennett, J. Engel, S. Pittel
We study the structure of nucleon pairs within a simple model consisting of a square well in three dimensions and a delta-function residual interaction between two weakly-bound par…
The Development and Migration of Concepts from Donor to Borrower Disciplines: Sublanguage Term Use in Hard & Soft Sciences
Robert M. Losee
Academic disciplines, often divided into hard and soft sciences, may be understood as "donor disciplines" if they produce more concepts than they borrow from other disciplines, or…
Black hole collisions from Brill-Lindquist initial data: predictions of perturbation theory
A. M. Abrahams, R. H. Price
The Misner initial value solution for two momentarily stationary black holes has been the focus of much numerical study. We report here analytic results for an astrophysically simi…
Threshold Corrections and Gauge Symmetry in Twisted Superstring Models
David M. Pierce
Threshold corrections to the running of gauge couplings are calculated for superstring models with free complex world sheet fermions. For two N=1 models, the t…
Applying black hole perturbation theory to numerically generated spacetimes
A. M. Abrahams, R. H. Price
Nonspherical perturbation theory has been necessary to understand the meaning of radiation in spacetimes generated through fully nonlinear numerical relativity. Recently, perturbat…
Treating Top Differently from Charm and Up
Paul H. Frampton
It now appears phenomenologically that the third family may be essentially different from the first two. Particularly the high value of the top quark mass suggests a special role.…
An elegant solution of the n-body Toda problem
Arlen Anderson
The solution of the classical open-chain n-body Toda problem is derived from an ansatz and is found to have a highly symmetric form. The proof requires an unusual identity involvin…
The Light, the Heavy and the Superheavy --- a Nonabelian Flavor Symmetry for the Full Hierarchy
Otto C. W. Kong
We give a preliminary report of a new quark mass matrix model basing on a symmetry embedding into a fully gauged $SU(5)\otimes SU(5)\otimes SU(2)…
Path integral approach to no-Coriolis approximation in heavy-ion collisions
K. Hagino, N. Takigawa, A. B. Balantekin +1
We use the two time influence functional method of the path integral approach in order to reduce the dimension of the coupled-channels equations for heavy-ion reactions based on th…
Einstein and Yang-Mills theories in hyperbolic form without gauge-fixing
A. Abrahams, A. Anderson, Y. Choquet-Bruhat +1
The evolution of physical and gauge degrees of freedom in the Einstein and Yang-Mills theories are separated in a gauge-invariant manner. We show that the equations of motion of th…
Exactly Solvable (0,2) Supersymmetric String Vacua With GUT Gauge Groups
Ralph Blumenhagen, Andreas Wisskirchen
We present a construction of modular invariant partition functions for heterotic (0,2) supersymmetric classical string vacua. This generalization of Gepner's construction yields GU…
