Descripción
To study the properties of elusive atmospheric neutrinos, the India-based Neutrino Observatory (INO) has been planned to be set up at Theni (Tamil Nadu), South India. INO will host a 50 ktons magnetized Iron CALorimeter (ICAL) detector for the determination of neutrino mass and mixing parameters which is one of the important issues for the leptonic sector in today’s particle physics. The detector will have three modules, each of size 16 m x 16 m x 14.5 m and consists of stack of 151 horizontal layers of 5.6 cm thick iron slab interleaved within 4 cm gap for the active detector element. Resistive Plate Chambers (RPCs) of dimension 2 m x 2 m, which have good time resolution (∼1ns) and spatial resolution (∼3 cm), will be used as active part of the detector.
We will report about the precision measurement analysis for the atmospheric neutrino oscillation parameters with the muon neutrino events, generated through Monte Carlo NUANCE event generator. The analysis has been performed using neutrino energy and muon direction as the observables. ICAL detector will be able to detect muon tracks and hadron showers produced by neutrino events. We have used the realistic resolutions and efficiencies obtained by the INO collaboration from a GEANT4-based simulation to reconstruct neutrino energy and muon direction. We will present the ICAL sensitivity for atmospheric neutrino mixing parameters (sin^2(θ_{23}) and (|∆m^2_{23}|) on the basis of marginalised χ2 analyses using neutrino energy and muon zenith angle binning scheme for the 10 years of running INO-ICAL detector.
