超对称左右对称模型的自发宇称破坏

Spontaneous Parity Violation in a Supersymmetric Left-Right Symmetric Model

Sudhanwa Patra, Anjishnu Sarkar, Utpal Sarkar, Urjit Yajnik

摘要:

我们提出了一种新的实现自发宇称破缺的超对称左右对称模型,避免了一些在以前的研究中遇到的问题。这种实现包括一个bitriplet和一个singlet,除了bidrilet扩展的最小超对称标准模型(MSSM)的希格斯部门。这个理论的超对称真空一般导致自发违反宇称,同时保持R宇称。该模型再现真空期望值的跷跷板关系,$v_L v_R \approx m_{EW}^2$有关的新的质量尺度$v_L$,$v_R$的电弱尺度$m_{EW}$,就像在非超对称的版本。$v_R$标度决定了重majorana中微子的质量标度,它与观测到的中微子质量之间存在II型跷跷板关系。

英文摘要:

We propose a novel implementation of spontaneous parity breaking in supersymmetric left-right symmetric model, avoiding some of the problems encountered in previous studies. This implementation includes a bitriplet and a singlet, in addition to the bidoublets which extend the Higgs sector of the Minimal Supersymmetric Standard Model (MSSM). The supersymmetric vacua of this theory are shown to lead generically to spontaneous violation of parity, while preserving R parity. The model is shown to reproduce the see-saw relation for vacuum expectation values, $v_L v_R \approx m_{EW}^2$ relating the new mass scales $v_L$, $v_R$ to the electroweak scale $m_{EW}$, just as in the non-supersymmetric version. The scale $v_R$ determines the mass scale of heavy majorana neutrinos, which gets related to the obeserved neutrino masses through type II see-saw relation.
