Measurement of Atmospheric Neutrino Mass-Squared Splittings at INO-ICAL Experiment

In the present work we explore the ability of the magnetized Iron Calorimeter detector (ICal) at the India-based Neutrino Observatory (INO) to identify the neutrinos and antineutrinos on an event by event basis. Consequently, the experimental observation of the difference of mass-squared splittings in \(\nu _\mu \) and \(\bar{\nu }_\mu \) oscillations at INO has been studied. The detector sensitivity is estimated so as to confirm a non-zero difference in the splittings for neutrinos and antineutrinos using charged current \(\nu _\mu \) and \(\bar{\nu }_\mu \) interactions with the detector under the influence of earth matter effect for ten years exposure of the detector. A \(\chi ^2\) is minimized with respect to observed parameters to find out the oscillation parameters for \(\nu _\mu \) and \(\bar{\nu }_\mu \) independently.
