Cosmological constant, brane tension and large hierarchy in a generalized Randall-Sundrum braneworld scenario
Saurya Das, Debaprasad Maity, Soumitra SenGupta
We consider a generalized Randall Sundrum (RS) brane world scenario with a cosmological constant induced on the visible brane. We show that for , resolution of the hierarc…
Gravitational anomalies: a recipe for Hawking radiation
Saurya Das, Sean P. Robinson, Elias C. Vagenas
We explore the method of Robinson and Wilczek for deriving the Hawking temperature of a black hole. In this method, the Hawking radiation restores general covariance in an effectiv…
Stability and hierarchy problems in string inspired braneworld scenarios
Saurya Das, Anindya Dey, Soumitra SenGupta
We generalise the RS braneworld model by taking into account a general stringy bulk containing the scalar dilaton field and the two-form Kalb-Ramond field, apart from gravity. Assu…
Leading Log Corrections to Bekenstein-Hawking Entropy
Saurya Das
We show that the Bekenstein-Hawking entropy associated with any black hole undergoes logarithmic corrections when small thermodynamic fluctuations around equilibrium are taken into…
Eikonal Approach to Planck Scale Physics
Saurya Das
We consider gravitational scattering of point particles with Planckian centre-of-mass energy and fixed low momentum transfers in the framework of general relativity and dilaton gra…
