Abstract
We investigate gravitino dark matter produced thermally at high temperatures and in decays of a longlived sneutrino We consider the NonUniversal Higgs Model and a generalized gauge mediation model and in each case identify sneutrino LOSP regions of the parameter space consistent with the mass of the Higgslike boson observed at the LHC We apply relevant collider and cosmological bounds including constraints from Big Bang Nucleosynthesis and from warm dark matter on large scale structures Generally we find allowed values of the reheating temperature T R below 109 GeV ie somewhat smaller than the values needed for thermal leptogenesis even with a conservative lower bound of 122 GeV on the Higgs mass Requiring mass values closer to 126 GeV implies T R below 107 GeV and the gravitino mass less than 10 GeVThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
