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…
