Supersymmetric flat directions and resonant gravitino production
Namit Mahajan, Raghavan Rangarajan, Anjishnu Sarkar
We study resonant gravitino production in the early Universe in the presence of SUSY flat directions whose large VEVs break some but not all gauge symmetries. We find that for a la…
Flat directions and gravitino production in SUSY models
Raghavan Rangarajan, Anjishnu Sarkar
Flat directions in supersymmetric models can get large vacuum expectation values in the early Universe which leads to a large mass for gauge bosons and gauginos. We point out that…
Kinetic and chemical equilibrium of the Universe and gravitino production
Raghavan Rangarajan, Anjishnu Sarkar
Flat directions in generic supersymmetric theories can change the thermal history of the Universe. A novel scenario was proposed earlier where the vacuum expectation value of the f…
