The Reach of INO for Atmospheric Neutrino Oscillation Parameters

The India-based Neutrino Observatory (INO) will host a 50 kt magnetized iron calorimeter (ICAL@INO) for the study of atmospheric neutrinos. Using the detector resolutions and efficiencies obtained by the INO collaboration from a full-detector GEANT4-based simulation, we determine the reach of this experiment for the measurement of the atmospheric neutrino mixing parameters (${\sin }^2{\theta }_{23}$ and $\mathrm{\mid }\mathrm{\Delta }{m}_{32}^2\mathrm{\mid }$). We also explore the sensitivity of this experiment to the deviation of ${\theta }_{23}$ from maximal mixing, and its octant.
