The Instanton Density at Finite Temperatures

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

For {\it low} T new strict results for the instanton density n(T) are reported. Using the PCAC methods, we express n(T) in terms of {\it vacuum} average values of certain operators, times their {\it calculated} T-dependence. At high T, we discuss the {\it applicability} limits of the perturbative results. We further speculate about possible behaviour of n(T) at TTcT\sim T_c.
