Title: 一次循环欧拉-海森堡作用在洛伦兹破坏的QED中的重新研究

Abstract: We discuss applications of the proper-time method in a Lorentz-violating extension of QED characterized by the modification of the mass sector through the addition of the term proportional to the antisymmetric tensor $H_{\mu\nu}$. Unlike other LV extensions of QED, in our case the one-loop Euler-Heisenberg-like action turns out to include only odd degrees of the stress tensor $F_{\mu\nu}$. Our result is shown to be UV finite, and it is confirmed using the Feynman diagrams framework. Show Chinese abstract

Abstract: 我们讨论了在由通过添加与反对称张量$H_{\mu\nu}$成正比的项修改质量部分的洛伦兹破坏扩展QED中，适当时间方法的应用。 与其他洛伦兹破坏(QED)扩展不同，在我们的案例中，一环欧拉-海森伯类似作用量仅包含应力张量$F_{\mu\nu}$的奇数次幂。 我们的结果被证明是紫外线有限的，并通过费曼图框架得到了确认。
