B-physics constraints on baryon number violating couplings: grand unification or R-parity violation
Debrupa Chakraverty, Debajyoti Choudhury
We investigate the role that baryon number violating interactions may play in phenomenology. Present in various grand unified theories, supersymmetric theories with R-parity vi…
Signals of R-parity violating supersymmetry in neutrino scattering at muon storage rings
Anindya Datta, Raj Gandhi, Biswarup Mukhopadhyaya +1
Neutrino oscillation signals at muon storage rings can be faked by supersymmetric (SUSY) interactions in an R-parity violating scenario. We investigate the -appearance signals f…
Probing the violation of equivalence principle at a muon storage ring via neutrino oscillation
Anindya Datta
We examine the possible tests of violation of the gravitational equivalence principle (VEP) at a muon storage ring via neutrino oscillation experiments. If the gravitational intera…
Trilinear Neutral Gauge Boson Couplings
Debajyoti Choudhury, Sukanta Dutta, Subhendu Rakshit +1
We study the CP even trilinear neutral gauge boson vertices at one-loop in the context of the Standard Model and the Minimal Supersymmetric Standard Model, assuming two of the vect…
Ultra-High Energy Neutrinos: A Review of Theoretical and Phenomenological Issues
Raj Gandhi
We review the phenomenology of ultra-high energy (UHE) neutrino detection. The motivations for looking for such neutrinos stemming from observational evidence and the potential for…
LHC Signature of the Minimal SUGRA Model with a Large Soft Scalar Mass
Utpal Chattopadhyay, Amitava Datta, Anindya Datta +2
Thanks to the focus point phenomenon, it is quite {\it natural} for the minimal SUGRA model to have a large soft scalar mass m_0 > 1 TeV. A distinctive feature of this model is an…
