65.1 Introduction The non-standard interactions (NSI's) of the neutrino are theoretically well motivated, and after the discovery of large θ_(13), there is a huge interest in the community to look for these NSI's in the planned/proposed neutrino experiments. These NSI's can arise due to the presence ofnew heavy particles [1, 2], or, very light mediators [3], which have not been discovered yet. The proposed ICAL detector is designed to detect the atmospheric neutrinos having multi-GeV energy, and traversing vast ranges of baselines through the Earth matter. In the presence of flavor changing neutral current interactions, the MSW resonance of neutrino in the Earth matter gets modified and the ICAL detector can play an important role to explore these NSI's. The ICAL detector is capable enough to efficiently reconstruct the momentum of μ~- (μ~+) produced in the charge-current interaction of v_μ ({formula}) with irons in the detector.~1 The hadrons are produced along with the μ± in deep-inelastic scattering processes in multi-GeV energy, and they carry important information about the initial neutrino. The energy of hadron {formula} is calibrated using the number of hits in the detector due to hadron shower [5]. We study the future sensitivity of ICAL detector to place limit~2 on the NSI's using the observables E_μ, cos θμ, and E/_(had) of each event.
