Indirect detection of dark matter at INO

Not scheduled


Dr Deepak Tiwari (PICO, University of Montreal)


Neutrino fluxes arising from WIMP annihilation in the center of the sun($\odot$), earth($\oplus$) and galaxy can leave detectable signatures at the proposed 50-kt Iron Calorimeter (ICAL)
detector at the upcoming India-Based Neutrino Observatory (INO). Although the atmospheric neutrinos will pose a
serious background to such signal neutrinos, exploiting the excellent angular resolution of the ICAL detector we can
suppress it considerably. The expected 90 % C.L. exclusion sensitivity limits for 500 kt-years exposure for $\tau^{+} \tau^{-}$ channel (100 % branching ratio)
for WIMP-nucleon Spin Dependent ($\sigma_{SD}$) and Spin Independent ($\sigma_{SI}$) cross-section
are found to be $\sigma_{SD,\odot} < 6.87\times 10^{-41}$ cm$^2$ and $\sigma_{SI,\odot} < 7.75\times 10^{-43}$ cm$^2$ for
the WIMP mass ($m_{\chi}$) = 25 GeV, and $\sigma_{SI,\oplus} =1.02\times 10^{-44}~\mathrm{cm}^2$ for $m_{\chi}$ =52.14 GeV.
