Description
Motivated by axion physics, the topological susceptibility at high temperature was calculated by several lattice groups. A comparison with the semi-classical calculation at high temperature is meaningful and the details of the instanton calculation is reviewed. The correct over-all factor in MSbar and high precision parametrization of the temperature dependence is presented.
