XENON1T constraints on neutrino non-standard interactions
Siddhartha Karmakar, Sujata Pandey
The new XENON1T observation of dark matter-electron scattering cross-section, along with further constraining many popular dark matter models, has indicated the possibility of new…
Strong constraints on non-standard neutrino interactions: LHC vs. IceCube
Sujata Pandey, Siddhartha Karmakar, Subhendu Rakshit
We find the constraints on various non-standard interactions (NSI) of neutrinos from monojet+MET searches at the Large Hadron Collider (LHC). Also, we show that the measurement of…
Relaxed constraints on the heavy scalar masses in 2HDM
Siddhartha Karmakar, Subhendu Rakshit
In the wake of new scalar searches at LHC in various channels, it is interesting to investigate the sacrosanctity of the constraints on the masses and couplings of the heavier scal…
Are We Looking at Neutrino Absorption Spectra at IceCube?
Siddhartha Karmakar, Sujata Pandey, Subhendu Rakshit
The observed spectrum of ultrahigh energy neutrinos at IceCube might be indicative of absorption of such neutrinos in ultralight dark matter halos. We point out that various featur…
Interactions of Astrophysical Neutrinos with Dark Matter: A model building perspective
Sujata Pandey, Siddhartha Karmakar, Subhendu Rakshit
We explore the possibility that high energy astrophysical neutrinos can interact with the dark matter on their way to Earth. Keeping in mind that new physics might leave its signat…
Alignment Limit in 2HDM: Robustness put to test
Siddhartha Karmakar, Subhendu Rakshit
In a two-Higgs-doublet model (2HDM), at the vicinity of the alignment limit, the extra contributions to the couplings of the SM-like Higgs with other particles can be subdominant t…
