Inflation, reheating, leptogenesis and bounds on soft supersymmetry breaking parameters
Imtiyaz Ahmad Bhat, Girish Kumar Chakravarty, Rathin Adhikari
In the no-scale supergravity with Type-I Seesaw model of Non-minimal supersymmetric standard model (NMSSM), we have analysed inflation, reheating and leptogenesis. A no-scale super…
Resurrecting Quartic and Quadratic inflaton potentials in two-field inflationary model
Suratna Das, Girish Kumar Chakravarty, Gaetano Lambiase +1
After the release of the PLANCK data, it is evident that inflationary paradigm has stood the test of time. Even though, it is difficult to realise inflationary paradigm in a partic…
Constraints on Born-Infeld gravity from the speed of gravitational waves after GW170817 and GRB 170817A
Soumya Jana, Girish Kumar Chakravarty, Subhendra Mohanty
The observations of gravitational waves from the binary neutron star merger event GW170817 and the subsequent observation of its electromagnetic counterparts from the gamma-ray bur…
Supergravity Model of Inflation and Explaining IceCube HESE Data via PeV Dark Matter Decay
Girish Kumar Chakravarty, Najimuddin Khan, Subhendra Mohanty
We construct an unified model of inflation and PeV dark matter with an appropriate choice of no-scale Kähler potential, superpotential and gauge kinetic function in terms of MSSM f…
Testing theories of Gravity and Supergravity with inflation and observations of the cosmic microwave background
Girish Kumar Chakravarty, Gaetano Lambiase, Subhendra Mohanty
Many extensions of Einstein's theory of gravity have been studied and proposed with various motivations like the quest for a quantum theory of gravity to extensions of anomalies in…
Plateau Inflation in -parity Violating MSSM
Girish Kumar Chakravarty, Ujjal Kumar Dey, Gaetano Lambiase +1
Inflation with plateau potentials give the best fit to the CMB observables as they predict tensor to scalar ratio stringently bounded by the observations from Planck and BICEP2/Kec…
