超对称性需要两个希格斯二重态吗?

Does Supersymmetry Require Two Higgs Doublets?

Masahiro Ibe, Arvind Rajaraman, Ze'ev Surujon

摘要:

本文讨论了一类新的低能超对称模型,其中Higgs扇区只包含一个二重态,例如H_u,而不包含H_d。手征规范异常取消对新的电弱荷电态。我们讨论了在建立这样的模型的主要挑战,并提出了几个模型,这些问题得到解决。由此产生的现象学可以在许多方面与MSSM区别开来,最明显的是与下型夸克和带电轻子相关的物理学。作为研究手征Higgs扇区的第一步,我们讨论了惰性Hd偶态的情形。我们表明,这样的模型的UV完成自然包括暗物质与新的,可口的耦合SM夸克。

英文摘要:

We discuss a new class of low energy supersymmetric models in which the Higgs sector includes a single doublet, for example H_u, but not H_d. Chiral gauge anomalies are canceled against new electroweak-charged states. We discuss the main challenges in building such models, and present several models where these issues are addressed. The resulting phenomenology can be distinguished from that of the MSSM in a number of ways, most notably in physics related to down-type quarks and charged leptons. As a first step toward a chiral Higgs sector, we discuss the scenario of an inert H_d doublet. We show that a UV completion of such model naturally includes dark matter with novel, flavorful couplings to SM quarks.
