摘要：

The behaviour of the broken CP symmetry at finite temperature is examined. This is achieved through the investigation of the neutron electric dipole moment d(n) induced by theta-term. By using thermal QCD sum rules, we find that below the critical temperature, the ratio \d(n)/theta\ slightly decreases but survives at temperature effects. This evolution implies that CP remains broken at finite temperature as required by Baryogenesis [1].
