Readdressing the hierarchy problem in a Randall-Sundrum scenario with bulk Kalb-Ramond background
Saurya Das, Anindya Dey, Soumitra SenGupta
We re-examine the fine tuning problem of the Higgs mass, when an antisymmetric two form Kalb-Ramond (KR) field is present in the bulk of a Randall-Sundrum (RS) braneworld. Taking i…

High frequency quasi-normal modes for black holes with generic singularities II: Asymptotically non-flat spacetimes
Archisman Ghosh, S. Shankaranarayanan, Saurya Das
The possibility that the asymptotic quasi-normal mode (QNM) frequencies can be used to obtain the Bekenstein-Hawking entropy for the Schwarzschild black hole -- commonly referred t…

Charged black holes in generalized dilaton-axion gravity
Sourav Sur, Saurya Das, Soumitra SenGupta
We study generic Einstein-Maxwell-Kalb-Ramond-dilaton actions, and derive conditions under which they give rise to static, spherically symmetric black hole solutions. We obtain new…
