Abstract

We study the relevance of neutrino oscillation data for sparticle decays that violate the t lepton number at the LHC, in the context of the Constrained Minimal Supersymmetric Extension of the Standard Model (CMSSM) and in SU(5) extensions of the theory. We study the conditions required for X2 ? X + t±µ± decays to yield observable tau flavour violation, for cosmologically interesting values of the neutralino relic density. We present detailed studies of the relevant supersymmetric parameter space and pay particular emphasis to signals from tau hadronisation, that are analysed using PYTHIA event simulation. © 2009 American Institute of Physics.
