自发的R宇称破坏:未来对撞机上的中微子衰变和中微子混合角

Spontaneous R-parity violation: Lightest neutralino decays and neutrino mixing angles at future colliders

M. Hirsch, W. Porod, A. Vicente

摘要:

研究了R宇称自发破缺模型中最轻超对称粒子的衰变。我们重点讨论了两种情况下,LSP要么是一个比诺或中性单重轻子。我们的工作这两种情况之间最重要的现象学差异,并讨论如何将它们从显式的R-宇称破缺模型。在这两种情况下,我们发现衰变分支比的某些比例与太阳或大气(和反应堆)中微子角。因此,自发的R宇称破坏是观测到的中微子质量的来源这一假设在LHC上是可以检验的。

英文摘要:

We study the decays of the lightest supersymmetric particle (LSP) in models with spontaneously broken R-parity. We focus on the two cases that the LSP is either a bino or a neutral singlet lepton. We work out the most important phenomenological differences between these two scenarios and discuss also how they might be distinguished from explicit R-Parity breaking models. In both cases we find that certain ratios of decay branching ratios are correlated with either the solar or the atmospheric (and reactor) neutrino angle. The hypothesis that spontaneous R-Parity violation is the source of the observed neutrino masses is therefore potentially testable at the LHC.
