自发R-宇称破缺与左右对称性

Spontaneous R-Parity Breaking and Left-Right Symmetry

Pavel Fileviez Perez, Sogee Spinner

摘要:

我们提出了一个简单的可重正化的左-右理论,其中R-宇称自发破缺,中微子质量通过I型跷跷板机制和R-宇称破缺产生。在这个理论中,R宇称和规范对称性被超中微子真空期望值破缺,不存在Majoron问题。SU(2)R和R宇称破坏尺度由超对称破缺尺度决定,使模型具有很好的预测性。我们通过中性伴子、电荷伴子、Z^'衰变和W_R衰变讨论了该理论的谱和可能的检验。

英文摘要:

We propose a simple renormalizable left-right theory where R-parity is spontaneously broken and neutrino masses are generated through the Type I seesaw mechanism and R-parity violation. In this theory R-parity and the gauge symmetry are broken by the sneutrino vacuum expectation values and there is no Majoron problem. The SU(2)_R and R-parity violation scales are determined by the SUSY breaking scale making the model very predictive. We discuss the spectrum and possible tests of the theory through the neutralinos, charginos, Z^' and W_R decays at the Large Hadron Collider.
