Description
To study the properties of elusive atmospheric neutrinos, the India-based Neutrino
Observatory (INO) has been planned to be set up at Theni (Tamilnadu), South India.
INO will host a 50 kt magnetized Iron CALorimeter (ICAL) detector for 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. Glass Resistive
Plate Chambers (RPCs) of dimension 2 m x 2 m, which has good time resolution (~1
ns) 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 neu-
trino oscillation parameters with the muon neutrino events, generated through Monte
Carlo NUANCE event generator. The analysis has been performed using neutrino en-
ergy and muon direction as the observables. ICAL detector will be able to detect muons
tracks and hadron showers produced by neutrino events. We have used the realistic
resolutions and eciencies 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 (sin2theta_23 and |delta m2_
23|) on the basis of marginalised chi2 analyses using neutrino energy and muon zenith angle
binning scheme for the 10 years of running INO-ICAL detector.
