The semi-classical approximation at high temperature revisited

11 Mar 2020 Boccaletti Alexander Nogradi Daniel

We revisit the semi-classical calculation of the size distribution of instantons at finite temperature in non-abelian gauge theories in four dimensions. The relevant functional determinants were first calculated in the seminal work of Gross, Pisarski and Yaffe and the results were used for a wide variety of applications including axions most recently...
