具有R-宇称自发破坏的最小规范U(1)_{ B-L }模型

Minimal gauged U(1)_{B-L} model with spontaneous R-parity violation

Vernon Barger, Pavel Fileviez Perez, Sogee Spinner

摘要:

我们研究了最小规范U(1)_{B-L}超对称模型,证明了它为自发R宇称破坏提供了一个吸引人的理论. U(1)_{B-L}和R宇称都被右手sneutrino的真空期望值破缺(与软超对称质量成正比),从而将B-L和软超对称标度联系起来。在这种情况下,我们发现一个一致的机制产生中微子质量和一个现实的质谱,所有没有扩展的最小超对称标准模型的希格斯扇区。我们讨论了最相关的对撞机信号和Z'规范玻色子和R宇称破坏之间的联系。

英文摘要:

We study the minimal gauged U(1)_{B-L} supersymmetric model and show that it provides an attractive theory for spontaneous R-parity violation. Both U(1)_{B-L} and R-parity are broken by the vacuum expectation value of the right-handed sneutrino (proportional to the soft SUSY masses), thereby linking the B-L and soft SUSY scales. In this context we find a consistent mechanism for generating neutrino masses and a realistic mass spectrum, all without extending the Higgs sector of the minimal supersymmetry standard model. We discuss the most relevant collider signals and the connection between the Z' gauge boson and R-parity violation.
