Probing Fermion-Portal Scalar Dark Matter through Charged Vector-Like Fermions at Future Muon Colliders
Songshaptak De, Tapoja Jha, Najimuddin Khan +1
We revisit a minimal fermion-portal scalar dark matter model consisting of a real singlet scalar dark matter candidate and additional vector-like singlet and doublet charged fermio…
Gravitational Wave Emissions from First Order Phase Transitions with Two Component FIMP Dark Matter
Madhurima Pandey, Avik Paul
We explore the emissions of the Gravitational Waves (GWs) from a strong first-order ekectroweak phase transition. To this end, a dark matter model has been investigated in Feebly I…
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…
Estimation of Baryon Asymmetry from Dark Matter Decaying into IceCube Neutrinos
Tista Mukherjee, Madhurima Pandey, Debasish Majumdar +1
The recent results of IceCube Neutrino Observatory include an excess of PeV neutrino events which appear to follow a broken power law different from the other lower energy neutrino…
IceCube PeV Neutrino Events from the Decay of Superheavy Dark Matter;an Analysis
Madhurima Pandey, Debasish Majumdar, Ashadul Halder
Considering the ultrahigh energy (UHE) neutrino events reported by IceCube in the PeV regime to have originated from the decay of superheavy dark matter, the IceCube UHE neutrino e…
Mass and Life Time of Heavy Dark Matter Decaying into IceCube PeV Neutrinos
Madhurima Pandey, Debasish Majumdar, Ashadul Halder +1
Considering that the ultrahigh energy (UHE) upgoing muon neutrino events around the PeV energy region observed by the IceCube are due to the decay of super heavy dark matter to neu…
Effects of Violation of Equivalence Principle on UHE Neutrinos at IceCube in 4 Flavour Scenario
Madhurima Pandey
If weak equivalence principle is violated then different types of neutrinos would couple differently with gravity and that may produce a gravity induced oscillation for the neutrin…
Unparticle Decay of Neutrinos and its Possible Signatures at a Detector for (3+1) Flavour Framework
Madhurima Pandey
We consider a scenario where ultra high energy neutrinos undergo unparticle decay during its passage from its cosmological source to Earth. The idea of unparticle had been first pr…
Probing a Four Flavour vis-a-vis Three Flavour Neutrino Mixing for UHE Neutrino Signals at a 1 Detector
Madhurima Pandey, Debasish Majumdar, Amit Dutta Banik
We consider a four flavour scenario for the neutrinos where an extra sterile neutrino is introduced with the three families of active neutrinos and study the deviation from three f…
Two Component Feebly Interacting Massive Particle (FIMP) Dark Matter
Madhurima Pandey, Debasish Majumdar, Kamakshya Prasad Modak
We explore the idea of an alternative candidate for particle dark matter namely Feebly Interacting Massive Particle (FIMP) in the framework of a two component singlet scalar model.…
Two component WIMP-FImP dark matter model with singlet fermion, scalar and pseudo scalar
Amit Dutta Banik, Madhurima Pandey, Debasish Majumdar +1
We explore a two component dark matter model with a fermion and a scalar. In this scenario the Standard Model (SM) is extended by a fermion, a scalar and an additional pseudo scala…
