标量场和汤川场论的Lorentz破坏重正化

Renormalization of Scalar and Yukawa Field Theories with Lorentz Violation

Alejandro Ferrero, Brett Altschul

摘要:

我们考虑一个标量场和旋量场的理论,它们通过汤川相互作用和φ ^[4]相互作用相互作用,拉格朗日量中包含洛伦兹破坏算子。我们计算了这个理论中的主要量子修正。理论的重正化性被明确地显示为单圈阶。在纯标量扇区中,计算可以推广到高阶,并包括有限项,因为理论可以根据其洛伦兹不变版本求解。

英文摘要:

We consider a theory of scalar and spinor fields, interacting through Yukawa and phi^4 interactions, with Lorentz-violating operators included in the Lagrangian. We compute the leading quantum corrections in this theory. The renormalizability of the theory is explicitly shown up to one-loop order. In the pure scalar sector, the calculations can be generalized to higher orders and to include finite terms, because the theory can be solved in terms of its Lorentz-invariant version.
