Implications of NANOGrav results and UV freeze-in in a fast-expanding Universe
Basabendu Barman, Amit Dutta Banik, Avik Paul
Recent pulsar timing data reported by the NANOGrav collaboration indicates the existence of a stochastic gravitational wave (GW) background at a frequency . W…
Common origin of radiative neutrino mass, dark matter and leptogenesis in scotogenic Georgi-Machacek model
Shao-Long Chen, Amit Dutta Banik, Ze-Kun Liu
We explore the phenomenology of the Georgi-Machacek model extended with two Higgs doublets and vector fermion doublets invariant under $SU(2)_L \times U(1)_Y\times \mathcal {Z}_4 \…
Two Component Singlet-Triplet Scalar Dark Matter and Electroweak Vacuum Stability
Amit Dutta Banik, Rishav Roshan, Arunansu Sil
We propose a two component dark matter set-up by extending the Standard Model with a singlet and a hypercharge-less triplet scalars, each of them being odd under different sy…
Leptophilic-portal Dark Matter in the Light of AMS-02 positron excess
Sayan Ghosh, Amit Dutta Banik, Eung Jin Chun +1
We revisit dark matter annihilation as an explanation of the positron excess reported recently by the AMS-02 satellite-borne experiment. To this end, we propose a particle dark mat…
The Violation of Equivalence Principle and Four Neutrino Oscillations for Long Baseline Neutrinos
Madhurima Pandey, Debasish Majumdar, Amit Dutta Banik +1
Violation of equivalence principle predicts that neutrinos of different flavor couple differently with gravity. Such a scenario can give rise to gravity induced flavor oscillations…
