Tev尺度右侧的自发R-宇称破坏

The Right Side of Tev Scale Spontaneous R-Parity Violation

Lisa L. Everett, Pavel Fileviez Perez, Sogee Spinner

摘要:

本文研究了最小超对称标准模型的一个简单推广,其中理论的阿贝尔部分由B-L和右手同位旋组成。在极小模型中,这种阿贝尔规范结构被右手中微子的非零真空期望值破缺为标准模型超荷规范群,导致自发的R宇称破缺.该理论可以作为在高尺度下实现的左右对称理论的低能有效理论出现。我们确定了该理论的质量谱,并讨论了中微子质量的产生和R宇称破坏相互作用。讨论了在大型强子对撞机上区分具有TeV尺度B-L破缺的R宇称破坏模型的可能性。

英文摘要:

We study a simple extension of the minimal supersymmetric Standard Model in which the Abelian sector of the theory consists of B-L and right-handed isospin. In the minimal model this Abelian gauge structure is broken to the standard model hypercharge gauge group by non-vanishing vacuum expectation values of the right-handed sneutrinos, resulting in spontaneous R-parity violation. This theory can emerge as a low energy effective theory of a left-right symmetric theory realized at a high scale. We determine the mass spectrum of the theory, and discuss the generation of neutrino masses and R-parity violating interactions. The possibility of distinguishing between R-parity violating models with a gauged B-L broken at the TeV scale at the Large Hadron Collider is discussed.
