A step towards exploring the features of Gravidilaton sector in Randall-Sundrum scenario via lightest Kaluza-Klein graviton mass
Sayantan Choudhury, Soumitra SenGupta
In this paper we study the role of the 5D Gauss-Bonnet corrections and two loop higher genus contribution to the gravity action in type IIB string theory inspired low energy superg…
Galileogenesis: A new cosmophenomenological zip code for reheating through R-parity violating coupling
Sayantan Choudhury, Arnab Dasgupta
In this paper we introduce an idea of leptogenesis scenario in higher derivative gravity induced DBI Galileon framework {\it aka Galileogenesis} in presence of one-loop R-parity vi…
Collider constraints on Gauss-Bonnet coupling in warped geometry model
Sayantan Choudhury, Soumya Sadhukhan, Soumitra SenGupta
In this paper the requirement of a warp solution in an Einstein-Gauss-Bonnet 5D warped geometry is shown to fix the signature of Gauss-Bonnet coupling (). Further, imposing…
Primordial blackholes and gravitational waves for an inflection-point model of inflation
Sayantan Choudhury, Anupam Mazumdar
In this article we provide a new closed relationship between cosmic abundance of primordial gravitational waves and primordial blackholes originated from initial inflationary pertu…
Thermodynamics of Charged Kalb Ramond AdS black hole in presence of Gauss-Bonnet coupling
Sayantan Choudhury, Soumitra SenGupta
We study the role of the Gauss-Bonnet corrections to the gravity action on the charged AdS black hole in presence of rank 3 antisymmetric Kalb Ramond tensor field strength. Analyzi…
An accurate bound on tensor-to-scalar ratio and the scale of inflation
Sayantan Choudhury, Anupam Mazumdar
In this paper we provide an accurate bound on primordial gravitational waves, i.e. tensor-to-scalar ratio for a general class of single-field models of inflation where inflat…
