II型2HDM中耦合的约化

Reduction of Couplings in the Type-II 2HDM

M. A. May Pech, M. Mondragón, G. Patellis, G. Zoupanos

AI总结:

本文在II型2HDM中证明顶Yukawa、希格斯四次和色规范耦合在高能边界存在重整化群不变的1圈约化关系,并由唯象可行性确定tanβ和新物理能标。

摘要:

耦合约化的思想在于寻找可重整化理论中看似独立的耦合之间满足重整化群不变性的关系。在本文中,我们证明了在II型双希格斯二重态模型的高能边界处,顶夸克Yukawa耦合、希格斯四次耦合与规范色耦合之间存在此类1圈关系。约化理论的唯象可行性给出了$\ anβ$的取值以及新物理可能出现的能标。

英文摘要:

The idea of reduction of couplings consists in the search for relations between seemingly independent couplings of a renormalizable theory that are renormalization group invariant. In this article, we demonstrate the existence of such 1-loop relations among the top Yukawa, the Higgs quartic and the gauge colour couplings of the Type-II Two Higgs Doublet Model at a high-energy boundary. The phenomenological viability of the reduced theory suggests the value of $\tanβ$ and the scale in which new physics may appear.
