破坏四个费米子模型的高能洛伦兹的重整化

Renormalization Of High-Energy Lorentz Violating Four Fermion Models

Damiano Anselmi, Emilio Ciuffoli

摘要:

研究了四个费米子模型中高能洛伦兹的单圈重整化。我们推导出一般公式,然后考虑一些具体的模型。研究了渐近自由的条件,给出了确定渐近自由域的实用方法。我们还指出,在某些模型的RG流包含“合理的”齐默尔曼轨迹,可能会隐藏新的对称性。

英文摘要:

We study the one-loop renormalization of high-energy Lorentz violating four fermion models. We derive general formulas and then consider a number of specific models. We study the conditions for asymptotic freedom and give a practical method to determine the asymptotic-freedom domain. We also point out that in some models the RG flow contains "rational" Zimmermann trajectories that might hide new symmetries.
