摘要
We study the temperature dependence of soft CP-invariance violation in a class of gauge theories based on the gauge group SU(2)L×U(1) and show that there exist physically acceptable domains of coupling parameters of the theory where CP-invariance violation persists at high temperatures. Such models have the potential to explain matter-antimatter asymmetry in the universe while at the same time providing a cure for the strong CP problem. © 1979 The American Physical Society.
