Neutrino masses, the cosmological constant and a stable universe in a Randall-Sundrum scenario
Paramita Dey, Biswarup Mukhopadhyaya, Soumitra SenGupta
The Randall-Sundrum model of warped geometry in a five-dimensional scenario, aimed at explaining the hierarchy between the Planck and electroweak scales, is intrinsically unstable…
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…
Supergravity can reconcile dark matter with lepton number violating neutrino masses
Biswarup Mukhopadhyaya, Soumitra SenGupta, Raghavendra Srikanth
Supersymmetry offers a cold dark matter candidate, provided that lepton number is {\em not violated by an odd number of units}. On the other hand, lepton number violation by even (…
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…
