Supermassive gravitinos, dark matter, leptogenesis and flat direction baryogenesis
Rouzbeh Allahverdi, Steen Hannestad, Asko Jokinen +2
In general the gravitino mass and/or the soft supersymmetry breaking masses in the observable sector can be much larger than the TeV scale. Depending on the relation between the ma…
Non-Gaussianity from Instant and Tachyonic Preheating
Kari Enqvist, Asko Jokinen, Anupam Mazumdar +2
We study non-Gaussianity in two distinct models of preheating: instant and tachyonic. In instant preheating non-Gaussianity is sourced by the local terms generated through the coup…
Seed perturbations for primordial magnetic fields from MSSM flat directions
Kari Enqvist, Asko Jokinen, Anupam Mazumdar
We demonstrate that the MSSM flat directions can naturally account for the seed magnetic fields in the early Universe. The non-zero vacuum expectation value of an MSSM flat directi…
Analytical and numerical properties of Affleck-Dine condensate formation
A. Jokinen
We present analytical and numerical properties of the coherently rotating Affleck-Dine condensate formed along MSSM flat directions with the radiative corrections to the mass terms…
