AI总结:

本文构建任意非阿贝尔规范群下的洛伦兹破缺标量QCD,并在最低阶计算发散量子修正与β函数,证明耦合满足特定关系时洛伦兹破缺部分尺度不变。

摘要:

在本工作中,我们构建了具有任意非阿贝尔规范群的洛伦兹破缺标量量子色动力学理论。该理论属于标准模型扩展框架所涵盖的模型类别。在该理论洛伦兹破缺参数的最低阶,我们计算了发散量子修正,包括该理论的重整化群β函数。结果表明,若各耦合之间满足某一特定关系,则洛伦兹破缺部分具有尺度不变性。

英文摘要:

In this work, we formulate the theory of Lorentz-violating scalar Quantum Chromodynamics with an arbitrary non-Abelian gauge group. This theory belongs to the class of models encompassed by the standard model extension framework. At the lowest order in the theory's Lorentz violation parameters, we calculate the divergent quantum corrections, including the renormalization group $β$-functions of the theory. The Lorentz-violating sector is shown to be scale invariant if there is a particular relation between the couplings.
