一般标量理论中的六圈Beta函数

Six-loop beta functions in general scalar theory

Alexander Bednyakov, Andrey Pikelner

摘要:

我们考虑一般的可重正化标量场理论,并推导出六圈β函数的所有参数在d = 4维内的$\overline{MS}$计划。我们没有明确计算相关的回路积分,但利用$O(n)$对称模型的反条款在文献中。我们考虑无量纲耦合和参数的质量尺度,范围从三线性自耦合的真空能量。我们使用所获得的结果来扩展重整化群方程的几个向量,矩阵和张量模型的六圈顺序。此外,我们应用我们的一般表达式,以获得新的贡献的β函数和反常尺寸的标量部门的两希格斯双重模型。

英文摘要:

We consider general renormalizable scalar field theory and derive six-loop beta functions for all parameters in d = 4 dimensions within the $\overline{MS}$-scheme. We do not explicitly compute relevant loop integrals but utilize $O(n)$-symmetric model counter-terms available in the literature. We consider dimensionless couplings and parameters with a mass scale, ranging from the trilinear self-coupling to the vacuum energy. We use obtained results to extend renormalization-group equations for several vector, matrix, and tensor models to the six-loop order. Also, we apply our general expressions to derive new contributions to beta functions and anomalous dimensions in the scalar sector of the Two-Higgs-Doublet Model.
