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…
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…
Split supersymmetry and the role of a light fermion in a supergravity-based scenario
Biswarup Mukhopadhyaya, Soumitra SenGupta
We investigate split supersymmetry (SUSY) within a supergravity framework, where local SUSY is broken by the F-term of a hidden sector chiral superfield X. With reasonably general…
