没有味问题的错误-Higgs相互作用及其对物理观测的影响

Wrong-Higgs Interactions without Flavor Problems and their Effects on Physical Observables

Kyu Jung Bae

摘要:

我们考虑了错误的希格斯相互作用,如III型双希格斯模型。通常,这种相互作用会导致风味问题。然而,如果新的Yukawa相互作用具有与标准模型(SM)相同的味道结构,我们就没有任何味道问题。在这项工作中,我们提出了一个微观模型的错误希格斯相互作用与SM的超对称性(SUSY)的背景下,并显示其唯象意义。从μ介子g-2和稀有B衰变的低能约束可以解除,它可以是可行的,有低质量的超粒子谱与轻暗物质,这是最近的实验,如DAMA/LIBRA,CDMS-II和CoGeNT的首选。我们还简要讨论了对撞机中Higgs衰变的修正。

英文摘要:

We consider the wrong-Higgs interactions such as type-III two Higgs doublet models. Generally, such interactions cause flavor problems. However, if new Yukawa interactions have the same flavor structure as that of the standard model(SM), we do not have any flavor problems. In this work we propose a microscopic model for the wrong-Higgs interactions aligned with SM ones in the context of supersymmetry(SUSY) and show their phenomenological implications. Low energy contraints from muon g-2 and rare B decays can be relieved and it can be viable to have low mass superparticle spectra with light dark matter which is preferred by recent experiments such as DAMA/LIBRA, CDMS-II and CoGeNT. We also briefly discuss modification of Higgs decay in colliders.
