Temperature Correlations of Quantum Spins

A. R. Its, A. G. Izergin, V. E. Korepin +1

Isotropic XY is considered. It describes interaction of quantum spins on 1-dimesional lattice. Alternatevly one can call the model XXO Hiesenberg antiferromagnet. We solved long st…

An Example of Semiclassical Instanton-Like Scattering: (1+1) Dimensional Sigma Model

V. A. Rubakov, D. T. Son, P. G. Tinyakov

A solution to the classical field equations in the massless (1+1)-dimensional O(3) sigma model is found, which describes a multi-particle instanton-like transition at high energy.…

On reflection positive formulation of chiral gauge theories on a lattice

Sergei V. Zenkin

A formulation of chiral gauge theories on a lattice which is both reflection positive and gauge invariant is discussed.

Landau-Ginzburg Topological Theories in the Framework of GKM and Equivalent Hierarchies

S. Kharchev, A. Marshakov, A. Mironov +1

We consider the deformations of ``monomial solutions'' to Generalized Kontsevich Model \cite{KMMMZ91a,KMMMZ91b} and establish the relation between the flows generated by these defo…

Exact String Solutions in 2+1-Dimensional De Sitter Spacetime

H. J. de Vega, A. V. Mikhailov, N. Sanchez

Exact and explicit string solutions in de Sitter spacetime are found. (Here, the string equations reduce to a sinh-Gordon model). A new feature without flat spacetime analogy appea…

Adjoint Fermions Induce QCD

S. Khokhlachev, Yu. Makeenko

We propose to induce QCD by fermions in the adjoint representation of the gauge group SU(N_c) on the lattice. We consider various types of lattice fermions: chiral, Kogut--Susskind…

The Problem of Large-N Phase Transition in Kazakov-Migdal Model of Induced QCD

S. Khokhlachev, Yu. Makeenko

We study the lattice gauge model proposed recently by Kazakov and Migdal for inducing QCD. We discuss an extra local Z_N which is a symmetry of the model and propose of how to cons…

Observable Majoron Emission in Neutrinoless Double Beta Decay

Z Berezhiani, A Yu Smirnov, J W F Valle

We consider a class of simplest Majoron models where neutrino- majoron couplings can be in the range leading to the observability of neutrinoless double be…

Reflection positive formulation of chiral gauge theories on a lattice

Sergei V. Zenkin

Gauge invariant chiral theories satisfying the reflection positivity is constructed on a lattice. This requires the introduction of "half gauge fields" defined some time ago by Bry…
