两希格斯偶线模型Stueckelberg扩展中新规范玻色子的物理性质

The physics of a new gauge boson in a Stueckelberg extension of the two-Higgs-doublet model

Grigoris Panotopoulos, Paula Tuzón

摘要:

利用D膜物理学构建的弦论提供了一个框架,其中同时出现了规范群中的额外阿贝尔因子、不止一个希格斯偶线和广义格林-施瓦茨机制等成分。出于在定向褶皱结构中获得标准模型的方向的工作,我们在目前的工作中研究了两个希格斯偶极子模型的Stueckelberg扩展。我们的模型的显著特点是:i)一个尖锐的衰变宽度的重规范玻色子,和ii)一个带电的希格斯玻色子有两个主要的衰变通道,在树水平上具有相等的分支比。

英文摘要:

String theory constructions using D-brane physics offer a framework where ingredients like extra abelian factors in the gauge group, more than one Higgs doublet and a generalized Green-Schwarz mechanism appear at the same time. Motivated by works towards the direction of obtaining the Standard Model in orientifold constructions, we study in the present work a Stueckelberg extension of the two-Higgs-doublet model. The distinctive features of our model are i) a sharp decay width for the heavy gauge boson, and ii) a charged Higgs boson having two main decay channels at tree level with equal branching ratios.
