Looking for Galactic Diffuse Dark Matter in INO-MagICAL Detector

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 ($\langle\sigma v\rangle$)anddecaylifetime($\tau$)ofdarkmatterat90\mathrm{\%}C\mathrm{.}L\mathrm{.}:$\langle\sigma v\rangle\leq 1.87,\times,10^{-24}$cm$^3$s$^{-1}$and$\tau\geq 4.8,\times,10^{24}$sfor$m_\chi$ = 10 GeV assuming the NFW as DM density profile.
