Affleck-Dine condensate, late thermalization and the gravitino problem
Rouzbeh Allahverdi, Anupam Mazumdar
In this clarifying note we discuss the late decay of an Affleck-Dine condensate by providing a no-go theorem that attributes to conserved global charges which are identified by the…
Unifying inflation and dark matter with neutrino masses
Rouzbeh Allahverdi, Bhaskar Dutta, Anupam Mazumdar
We propose a simple model where a {\it gauge invariant inflaton} is responsible for cosmic inflation and generates the seed for structure formation, while its relic {\it thermal} a…
Probing the parameter space for an MSSM inflation and the neutralino dark matter
Rouzbeh Allahverdi, Bhaskar Dutta, Anupam Mazumdar
The flat directions LLe and udd within the minimal supersymmetric Standard Model provide all the necessary ingredients for a successful inflation with the right amplitude of the sc…
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…
Heavy particle production during reheating
Rouzbeh Allahverdi, Manuel Drees
We discuss production of heavy partciles during reheating. We find that the very energetic inflaton decay products can contribute to the production of massive stable particles, eit…
Baryogenesis in models with large extra dimensions
Anupam Mazumdar, Rouzbeh Allahverdi, Kari Enqvist +1
We describe how difficult it is to realise baryogenesis in models where the fundamental scale in nature is as low as TeV. The problem becomes even more challenging if we assume tha…
