Looking for Galactic Diffuse Dark Matter in INO-MagICAL Detector

Abstract

The Weakly Interacting Massive Particle (WIMP) is a popular particle physics candidate for the dark matter (DM). It can annihilate and/or decay to neutrino and antineutrino pair. The proposed 50 kt Magnetized Iron CALorimeter (MagICAL) detector at the India-based Neutrino Observatory (INO) can observe these pairs over the conventional atmospheric neutrino and antineutrino fluxes. If we do not see any excess of events in ten years, then INO-Magical can place competitive limits on self-annihilation cross-section ($⟨\sigma v⟩$) and decay lifetime ($\tau$) of dark matter at 90\% C.L.: $⟨\sigma v⟩\le 1.87\times 10^{-24}$ cm${}^3$ s${}^{-1}$ and $\tau \ge 4.8\times 10^{24}$ s for $m_{\chi }$ = 10 GeV assuming the NFW as DM density profile.
