MeV to multi-TeV thermal WIMPs: most conservative limits
Koushik Dutta, Avirup Ghosh, Arpan Kar +1
We consider a weakly interacting massive particle (WIMP) dark matter (DM) annihilating into all possible Standard Model (SM) particle pairs, including the SM neutrinos, via -wav…
Halo-independent bounds on the non-relativistic effective theory of WIMP-nucleon scattering from direct detection and neutrino observations
Sunghyun Kang, Arpan Kar, Stefano Scopel
We combine experimental constraints from direct detection searches and from neutrino telescopes looking for WIMP annihilations in the Sun to derive halo-independent bounds on each…
Searching for relativistic axions in the sky
Arpan Kar, Tanmoy Kumar, Sourov Roy +1
Relativistic axions produced in decays of dark matter (DM) partially convert to photons after traversing the galactic magnetic field, gi…
Improved White Dwarves Constraints on Inelastic Dark Matter and Left-Right Symmetric Models
Anirban Biswas, Arpan Kar, Hyomin Kim +2
WIMPs can be captured in compact stars such as white dwarves (WDs) leading to an increase in the star luminosity through their annihilation process. We show that when the WIMP inte…
A general study of decaying scalar dark matter: existing limits and projected radio signals at the SKA
Koushik Dutta, Avirup Ghosh, Arpan Kar +1
We consider a decaying scalar dark matter (DM) with mass in the range 10 GeV - 10 TeV and vary the branching ratios of all possible two-body SM final states (excluding and in…
