Probing neutralino properties in minimal supergravity with bilinear R-parity violation

摘要

Supersymmetric models with bilinear R-parity violation (BRPV) can account forthe observed neutrino masses and mixing parameters indicated by neutrinooscillation data. We consider minimal supergravity versions of BRPV where thelightest supersymmetric particle (LSP) is a neutralino. This is unstable, witha 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 asmass, lifetime and branching ratios, and discuss their relation to neutrinoproperties.
