Unitarity violation in sequential neutrino mixing in a model of extra dimensions
Subhaditya Bhattacharya, Paramita Dey, Biswarup Mukhopadhyaya
We investigate the possibility of unitarity violation in the sequential neutrino mixing matrix in a scenario with extra compact spacelike dimensions. Gauge singlet neutrinos are as…
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…
The impossibility of heavy neutrino dark matter in the Littlest Higgs Model with T-parity: constraints from direct search
Paramita Dey, Sudhir Kumar Gupta, Biswarup Mukhopadhyaya
We consider the Littlest Higgs Model with T-parity (LHT), in the parameter region where a heavy neutrino is the lightest T-odd particle (LTP). Having emphasized that this correspon…
Some consequences of a Higgs triplet
Paramita Dey, Anirban Kundu, Biswarup Mukhopadhyaya
We consider an extension of the scalar sector of the Standard Model with a single complex Higgs triplet . Such extensions are the most economic, model-independent way of generat…
Neutrinos in flat extra dimension: towards a realistic scenario
Asmaa Abada, Paramita Dey, Grégory Moreau
We consider the simple extension of the Standard Model in which an additional right handed neutrino propagates along a flat extra dimension, while the Standard Model fields are con…
