摘要:

双线性R宇称破缺的超对称模型(BRPV)可以解释由中微子振荡数据所指示的中微子质量和混合参数。我们考虑BRPV的最小超引力版本,其中最轻的超对称粒子(LSP)是中性伴子。这是不稳定的,有足够大的衰变长度可以在欧洲核子研究中心的大型强子对撞机(LHC)上检测到。我们分析了LHC势,确定了LSP的性质,如质量,寿命和分支比,并讨论了它们与中微子性质的关系。

英文摘要:

Supersymmetric models with bilinear R-parity violation (BRPV) can account for the observed neutrino masses and mixing parameters indicated by neutrino oscillation data. We consider minimal supergravity versions of BRPV where the lightest supersymmetric particle (LSP) is a neutralino. This is unstable, with a large enough decay length to be detected at the CERN Large Hadron Collider (LHC). We analyse the LHC potential to determine the LSP properties, such as mass, lifetime and branching ratios, and discuss their relation to neutrino properties.
