Common origin of baryon asymmetry, dark matter and neutrino mass
Anirban Biswas, Sandhya Choubey, Laura Covi +1
In this work, we explain three beyond standard model (BSM) phenomena, namely neutrino masses, the baryon asymmetry of the Universe and Dark Matter, within a single model and in eac…
Sensitivity study of Protvino to ORCA (P2O) experiment: Effect of antineutrino run, background and systematics
Sandhya Choubey, Monojit Ghosh, Dipyaman Pramanik
There is a proposal to send a neutrino beam from the Protvino accelerator complex located in Russia to the detector facility called `Oscillation Research with Cosmics in the Abyss'…
SModelS v1.2: long-lived particles, combination of signal regions, and other novelties
Federico Ambrogi, Juhi Dutta, Jan Heisig +8
SModelS is an automatised tool enabling the fast interpretation of simplified model results from the LHC within any model of new physics respecting a symmetry. With…
Exploring fake solutions in the sterile neutrino sector at long-baseline experiments
Sandhya Choubey, Debajyoti Dutta, Dipyaman Pramanik
Active-sterile neutrino mixing is known to affect the neutrino oscillation probabilities at both short as well as long-baselines. In particular, constraints on active-sterile neutr…
Sbottoms as probes to MSSM with nonholomorphic soft interactions
Utpal Chattopadhyay, AseshKrishna Datta, Samadrita Mukherjee +1
Presence of nonholomorphic soft SUSY breaking terms is known to be a possibility in the popular setup of the Minimal Supersymmetric Standard Model (MSSM). It has been shown that su…
Mixed WIMP-axion dark matter
Suman Chatterjee, Anirban Das, Tousik Samui +1
We study the experimental constraints on a model of a two-component dark matter, consisting of the QCD axion, and a scalar particle, both contributing to the dark matter relic abun…
