Note on the Thermal Behavior of the Neutron Electric Dipole Moment from QCD sum rules

arXiv:hep-ph/0010324 · doi:10.1088/0954-3899/27/11/308

Abstract

We use the method of thermal QCD sum rules to investigate the effects of temperature on the neutron electric dipole moment d_n induced by the vacuum \barθ-angle. Then, we analyze and discuss the thermal behaviour of the ratio {d_n \over \barθ} in connection with the restoration of the strong CP symmetry breaking.
