Probing Unified Origin of Dark Matter and Baryon Asymmetry at PAMELA/Fermi
Kazunori Kohri, Anupam Mazumdar, Narendra Sahu +1
We propose an unified model of dark matter and baryon asymmetry in a lepto-philic world above the electroweak scale. We provide an example where the inflaton decay products subsequ…
Inflation, baryogenesis and gravitino dark matter at ultra low reheat temperatures
Kazunori Kohri, Anupam Mazumdar, Narendra Sahu
It is quite possible that the reheat temperature of the universe is extremely low close to the scale of Big Bang nucleosynthesis, i.e. MeV. At such low reheat temp…
Gravitational waves from the fragmentation of a supersymmetric condensate
Alexander Kusenko, Anupam Mazumdar, Tuomas Multamaki
We discuss the production of gravity waves from the fragmentation of a supersymmetric condensate in the early universe. Supersymmetry predicts the existence of flat directions in t…
Newton's constant in f(R,R_{μν}R^{μν},\Box R) theories of gravity and constraints from BBN
Savvas Nesseris, Anupam Mazumdar
We consider corrections to the Einstein-Hilbert action which contain both higher order and nonlocal terms. We derive an effective Newtonian gravitational constant applicable at the…
Inflation with a Negative Cosmological Constant
Tirthabir Biswas, Anupam Mazumdar
We find a unique way of realizing inflation through cyclic phases in an universe with negative vacuum energy. According to the second law of thermodynamics entropy monotonically in…
