标准模型推广中的第四代t-素数

The Fourth Generation t-prime in Extensions of the Standard Model

Erin De Pree, Gardner Marshall, Marc Sher

摘要:

我们研究了第四代t'夸克在标准模型的各种扩展中的作用。在Randall-Sundrum模型中,衰变t '--> t Z具有大的分支比,可以在大型强子对撞机(LHC)上检测到。我们也看看两个希格斯二重模型I,II和III,并注意到,在后者中,分支比的t' --> t H,其中H是希格斯标量或赝标量,是巨大的,我们讨论在大型强子对撞机的检测。对最小超对称标准模型也作了一些评论。

英文摘要:

We study the effects of a fourth generation t' quark in various extensions of the standard model. In the Randall-Sundrum model, the decay t'--> t Z has a large branching ratio that could be detected at the Large Hadron Collider (LHC). We also look at the two-Higgs doublet models I, II and III, and note that, in the latter, the branching ratio of t' --> t H, where H is a Higgs scalar or pseudoscalar, is huge and we discuss detection at the LHC. A few comments about the minimal supersymmetric standard model are also included.
