TL;DR
This paper reviews the calculation of radiative corrections to the Chern-Simons-like term in field theory, considering zero and finite temperature and gravity, using dimensional regularization.
Contribution
It provides explicit calculations of radiative corrections to the Chern-Simons-like term across different physical contexts, highlighting the role of dimensional regularization.
Findings
Radiative corrections are computed explicitly at zero and finite temperature.
Results are obtained within the framework of dimensional regularization.
The study extends to gravity theories, broadening the understanding of Lorentz and CPT violation.
Abstract
In this brief review we explicitly calculate the radiative corrections to the Chern-Simons-like term in the cases of zero and finite temperature, and in the gravity theory. Our results are obtained under the general guidance of dimensional regularization.
