摘要：
In this paper, we present a study to measure the differences between the atmospheric neutrino and antineutrino oscillations in the Iron-Calorimeter detector at the India-based Neutrino Observatory experiment. Charged-current nu(mu) and (nu) over bar (mu) interactions with the detector under the influence of the Earth matter effect have been simulated for ten years of exposure. The observed nu(mu) and (v) over bar (mu) event spectra are separately binned into direction and energy bins, and chi(2) is minimized with respect to each bin to extract the oscillation parameters for nu(mu) and (nu) over bar (mu) separately. We then present the ICAL sensitivity to confirm a nonzero value of the difference in the atmospheric mass squared of neutrinos and antineutrinos, i.e.,vertical bar Delta m(32)(2)vertical bar - vertical bar Delta(m) over bar (2)(32 vertical bar) .
