Charged Higgs effects in IceCube: PeV events and NSIs
Ujjal Kumar Dey, Newton Nath, Soumya Sadhukhan
Extensions of the Standard Model with charged Higgs, having a non-negligible coupling with neutrinos, can have interesting implications vis-à-vis neutrino experiments. Such models…
Prospects of Migdal Effect in the Explanation of XENON1T Electron Recoil Excess
Ujjal Kumar Dey, Tarak Nath Maity, Tirtha Sankar Ray
The XENON1T experiment has recently announced the observation of an excess in electron recoil events at energy range of keV with a signal significance over the Standa…
Connecting ANITA Anomalous Events to a Non-thermal Dark Matter Scenario
Debasish Borah, Arnab Dasgupta, Ujjal Kumar Dey +1
The ANtarctic Impulsive Transient Antenna (ANITA) collaboration has observed two EeV-energy, upward going events originating from below the horizon. As no standard model (SM) parti…
An inverse seesaw model with global symmetry
Ujjal Kumar Dey, Takaaki Nomura, Hiroshi Okada
We propose an inverse seesaw model based on hidden global symmetry in which we realize tiny neutrino masses with rather natural manner taking into account relevant experim…
Boosting Assisted Annihilation for a Cosmologically Safe MeV Scale Dark Matter
Ujjal Kumar Dey, Tarak Nath Maity, Tirtha Sankar Ray
Assisted annihilation generates thermal sub-GeV dark matter through a novel annihilation between a pair of dark matter and standard-model-like states, called the "assister". We sho…
Non-Standard Neutrino Interactions in a Modified 2HDM
Ujjal Kumar Dey, Newton Nath, Soumya Sadhukhan
In the traditional neutrinophilic two-Higgs doublet model (2HDM), there is no non-standard neutrino interaction (NSI) as the interactions between the Standard Model fermions wit…
