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…
Bulk antisymmetric tensor fields in a Randall-Sundrum model
Biswarup Mukhopadhyaya, Somasri Sen, Soumitra SenGupta
We consider bulk antisymmetric tensor fields of various ranks in a Randall-Sundrum scenario. We show that, rank-2 onwards, the zero-modes of the projections of these fields on the…
Slowly Rotating Dilaton Black hole In Anti-de Sitter Spacetime
Tanwi Ghosh, Soumitra SenGupta
Rotating dilaton black hole solution for asymptotically anti-de Sitter spacetime are obtained in the small angular momentum limit with an appropriate combination of three Liouville…
Constraining the Randall-Sundrum modulus in the light of recent PVLAS data
Debaprasad Maity, Sourov Roy, Soumitra SenGupta
Recent PVLAS data put stringent constraints on the measurement of birefringence and dichroism of electromagnetic waves travelling in a constant and homogeneous magnetic field. Ther…
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…
