Non-standard neutrino interactions (NSI) involved in neutrino propagation inside Earth matter could potentially alter atmospheric neutrino fluxes. In this work, we look at the impact of these NSI on the signal at the ICAL detector to be built at the India-based Neutrino Observatory (INO). We show how the sensitivity to the neutrino mass hierarchy of ICAL changes in the presence of NSI. The mass hierarchy sensitivity is shown to be rather sensitive to the NSI parameters eµ and eτ , while the dependence on µτ and τ τ is seen to be very mild, once the χ 2 is marginalised over oscillation and NSI parameters. If the NSI are large enough, the event spectrum at ICAL is expected to be altered and this can be used to discover new physics. We calculate the lower limit on NSI parameters above which ICAL could discover NSI at a given C.L. from 10 years of data. If NSI were too small, the null signal at ICAL can constrain the NSI parameters. We give upper limits on the NSI parameters at any given C.L. that one is expected to put from 10 years of running of ICAL. Finally, we give C.L. contours in the NSI parameter space that is expected to be still allowed from 10 years of running of the experiment.

“…The charge of the muon is also identified in the process. While a muon momentum resolution of about 10-15% was obtained in the few GeV range of interest, the direction resolution was found to be better than a degree [8]. Hadron resolutions were much worse in comparison, and were determined by calibrating the hadron energy to the number of hits in the shower [9].…”

The India-based Neutrino Observatory (INO) is a proposed underground facility located in India that will primarily house the magnetised Iron CALorimeter (ICAL) detector to study atmospheric neutrinos produced by interactions of cosmic rays with Earth's atmosphere. The physics goal is to to make precision measurements of the neutrino mixing and oscillation parameters through such a study. We present here the results from detailed simulations studies, as well as a status report on the project. In particular, we highlight the sensitivity of ICAL to the open issue of the neutrino mass ordering, which can be determined independent of the CP phase at ICAL.

“…The hits by a muon form a track-like feature, while the hadron hits produce a shower. The muon momentum reconstruction in ICAL has been done through a Kalman-filter based track finding and fitting algorithm [5,7]. The ICAL detector is optimized for the detection of muons propagating in the detector, identification of their charges, and for accurate determination of their energies and directions.…”

The India-based Neutrino Observatory (INO) is an underground laboratory to be located in the Bodi West Hills, in the Theni district of Tamil Nadu in South India. The main experiment at INO is a magnetized iron calorimeter (ICAL) which will study the oscillations in the atmospheric neutrino sector. The ICAL will primarily aim at distinguishing the neutrino mass hierarchy through the study of the Earth's matter effects in the atmospheric ν µ andν µ . It will also determine the atmospheric neutrino mixing parameters with a fine precision and will probe the hints of new physics. The ICAL physics motivations, the detector description and present status of the detector simulation and physics reach studies are presented here.
