非极小统一模型中非单重态F项的非普适Gaugino质量

Non-universal gaugino masses from non-singlet F-terms in non-minimal unified models

Stephen P. Martin

摘要:

在低能超对称性的唯象研究中,在表观规范耦合统一的尺度附近,运行的高吉诺质量经常被认为是相等的。然而,许多已知的机制可以避免这种普适性,即使在统一规范相互作用的模型中。一个例子是F项真空期望值,它是标准模型规范群下的单线态,但在包含标准模型规范群的群的两个伴随表示的对称乘积中进行非平凡变换。本文计算了SO(10)和E_6及其子群的非单重态表象中F项所对应的Gaugino质量比,推广了SU(5)的已知结果。SO(10)结果纠正了文献中一些长期存在的错误。

英文摘要:

In phenomenological studies of low-energy supersymmetry, running gaugino masses are often taken to be equal near the scale of apparent gauge coupling unification. However, many known mechanisms can avoid this universality, even in models with unified gauge interactions. One example is an F-term vacuum expectation value that is a singlet under the Standard Model gauge group but transforms non-trivially in the symmetric product of two adjoint representations of a group that contains the Standard Model gauge group. Here, I compute the ratios of gaugino masses that follow from F-terms in non-singlet representations of SO(10) and E_6 and their sub-groups, extending well-known results for SU(5). The SO(10) results correct some long-standing errors in the literature.
