Constraints on a mixed inflaton and curvaton scenario for the generation of the curvature perturbation
G. Lazarides, R. Ruiz de Austri, R. Trotta
We consider a supersymmetric grand unified model which naturally solves the strong CP and mu problems via a Peccei-Quinn symmetry and leads to the standard realization of hybrid in…
Axino Dark Matter and the CMSSM
Laura Covi, Leszek Roszkowski, Roberto Ruiz de Austri +1
If the axino is the lightest superpartner and satisfies cosmological bounds, including a preferred range of the relic abundance of cold dark matter, then the usual stringent constr…
Leptogenesis through direct inflaton decay to light particles
Thomas Dent, George Lazarides, Roberto Ruiz de Austri
We present a scenario of nonthermal leptogenesis following supersymmetric hybrid inflation, in the case where inflaton decay to both heavy right handed neutrino and SU(2)_L triplet…
