Lorentz-CPT破坏、辐射修正和有限温度

Lorentz-CPT violation, radiative corrections and finite temperature

F. A. Brito, J. R. Nascimento, E. Passos, A. Petrov

摘要:

在这项工作中,我们研究了辐射诱导的陈-西蒙斯类条款在四维零和有限的温度。在CPT破坏耦合$b_μ$中,我们采用了将费米子传播子合理化到首阶的方法。在这种方法中,我们已经表明,虽然陈-西蒙斯项的系数可以在零温度或有限温度下在不同的正则化方案中明确地找到,但它仍然是未知的。我们观察到在有限温度和零温度下获得的结果之间的对应关系。

英文摘要:

In this work we investigate the radiatively induced Chern-Simons-like terms in four-dimensions at zero and finite temperature. We use the approach of rationalizing the fermion propagator up to the leading order in the CPT-violating coupling $b_μ$. In this approach, we have shown that although the coefficient of Chern-Simons term can be found unambiguously in different regularization schemes at zero or finite temperature, it remains undetermined. We observe a correspondence among results obtained at finite and zero temperature.
