Gravitino Dark Matter in Split Supersymmetry with Bilinear R-Parity Violation

Presented by Mr. Boris PANES on 25 Jul 2014 from 17:10 to 17:30
Type: Particle Cosmology
Track: Particle Cosmology


In Split-SUSY with BRpV we show that the Gravitino DM solution is consistent with experimental evidence on its relic density and life-time. We arrive to this conclusion performing a complete numerical and algebraic study of the parameter space, including constraints from the recently determined Higgs mass, updated neutrino physics, and BBN constraints to NLSP decays. The Higgs mass requires a relatively low Split-SUSY mass scale, which is naturally smaller than usual values for reheating temperature, allowing the use of the standard expression for the relic density. We include restrictions from neutrino physics with three generations, and notice an impact on the gravitino decay via the atmospheric neutrino mass scale. We calculate the neutralino decay and find it consistent with BBN. We mention some implications on indirect DM searches, but this work should be complemented with an exhaustive study of the different channels.
