Magnetic Screening in Thermal Yang-Mills Theories

Abstract

We develop a semiclassical method to calculate the density of magnetic monopoles in non-abelian gauge theories at finite temperature in the dilute gas approximation. This quantity is related to the inverse magnetic screening length for which we obtain ${\mu }_M=0.255g^{2}T$ in SU(2).
