Cosmological Constraints on MFV SUSY

Abstract

We study cosmological constraints in the context of $R$-parity violating MFV SUSY and find it is driven to $\tan (\beta )\approx 1$. These constraints are from two sources: first from the requirement that baryon number violation not undo baryogenesis and second that the flux of decay products from gravitino dark matter not exceed that observed by experiments such as PAMELA and Fermi LAT. The latter discussion favors relatively low gravitino masses of a few GeV.
