Light Neutralinos in B-Decays
Rathin ADhikari, Biswarup Mukhopadhyaya
We consider the decays of a -meson into a pair of lightest supersymmetric particles (LSP) in the minimal supersymmetric standard model. It is found that the parameter space fo…
Triplet Higgs bosons at colliders
R. M. Godbole, B. Mukhopadhyaya, M. Nowakowski
We investigate the possibility of probing the triplet Higgs boson sector via single charged Higgs production in the process , at high energy electron-positro…
Can We Identify a Light Neutralino in B-Factories
Rathin Adhikari, Biswarup Mukhopadhyaya
If a light gaugino sector exists, then the lightest supersymmetric particle (LSP) has a chance of being pair-produced in rare B-decays. As a consequence of neutral flavour violatio…
Scalar three-body decays and signals for new physics
Rathin Adhikari, Biswarup Mukhopadhyaya
If massive invisible particles are pair-produced in a three-body decay, then the energy distribution of the other (visible) product is sensitive to the mass of the invisible pair.…
Two-Loop Neutrino Masses and the Solar Neutrino Problem
Debajyoti Choudhury, Raj Gandhi, J. A. Gracey +1
The addition of singlet right-handed neutrinos to the Standard Model leads to radiatively generated mass corrections for the doublet neutrinos. For those neutrinos w…
