摘要

By using thermal QCD sum rules to investigate the θ induced neutron electric dipole moment d_n, we have examined the behaviour of broken CP symmetry at finite temperature. We find that, below the critical temperature, the ratio | d_n/θ| slightly decreases but survives at temperature effects, implying T nonrestoration of CP-invariance.
