“…The NUANCE [4] simulation suggests that the fraction of the different types of hadrons produced in the detector is π + : π − : π 0 :: 0.38 : 0.25 : 0.34, with the remaining 3% contribution coming mainly from kaons [10]. While the response of the detector to π + and π − is almost identical as seen earlier, its response to the electromagnetic part of the hadron shower that originates from π 0 is different.…”

“…The directions are binned into 5 zenith angle bins, and the distributions of number of hits is recorded. The ratio of the rms width of the distribution and its mean is used as a measure of the energy resolution [10]. Since there is only a mild dependence on the hadron direction, and the direction of hadron itself cannot be determined yet with a good confidence, we continue to use the directionaveraged results in the future analyses in this Report.…”

The upcoming 50 kt magnetized iron calorimeter (ICAL) detector at the India-based Neutrino Observatory (INO) is designed to study the atmospheric neutrinos and antineutrinos separately over a wide range of energies and path lengths. The primary focus of this experiment is to explore the Earth matter effects by observing the energy and zenith angle dependence of the atmospheric neutrinos in the multi-GeV range. This study will be crucial to address some of the outstanding issues in neutrino oscillation physics, including the fundamental issue of neutrino mass hierarchy. In this document, we present the physics potential of the detector as obtained from realistic detector simulations. We describe the simulation framework, the neutrino interactions in the detector, and the expected response of the detector to particles traversing it. The ICAL detector can determine the energy and direction of the muons to a high precision, and in addition, its sensitivity to multi-GeV hadrons increases its physics reach substantially. Its charge identification capability, and hence its ability to distinguish neutrinos from antineutrinos, makes it an efficient detector for determining the neutrino mass hierarchy. In this report, we outline the analyses carried out for the determination of neutrino mass hierarchy and precision measurements of atmospheric neutrino mixing parameters at ICAL, and give the expected physics reach of the detector with 10 years of runtime. We also explore the potential of ICAL for probing new physics scenarios like CPT violation and the presence of magnetic monopoles. v Physics Potential of ICAL at INO vi PrefaceThe past two decades in neutrino physics have been very eventful, and have established this field as one of the flourishing areas of high energy physics. Starting from the confirmation of neutrino oscillations that resolved the decades-old problems of the solar and atmospheric neutrinos, we have now been able to show that neutrinos have nonzero masses, and different flavors of neutrinos mix among themselves. Our understanding of neutrino properties has increased by leaps and bounds. Many experiments have been constructed and envisaged to explore different facets of neutrinos, in particular their masses and mixing.The Iron Calorimeter (ICAL) experiment at the India-based Neutrino Observatory (INO) [1] is one of the major detectors that is expected to see the light of the day soon. It will have unique features like the ability to distinguish muon neutrinos from antineutrinos at GeV energies, and measure the energies of hadrons in the same energy range. It is therefore well suited for the identification of neutrino mass hierarchy, the measurement of neutrino mixing parameters, and many probes of new physics. The site for the INO has been identified, and the construction is expected to start soon. In the meanwhile, the R&D for the ICAL detector, including the design of its modules, the magnet coils, the active detector elements and the associated electronics, has been underway over the past deca...

“…(1) is for the ideal case when the detector has perfect resolutions and 100% efficiencies. In this analysis, realistic resolutions and efficiencies obtained from GEANT-4-based simulation studies of ICAL [25][26][27][28][29] have been incorporated; this not only reduces the overall events due to the reconstruction efficiency factor but also smears out the final state (or observed) muon energy and direction and that of the hadron energy as well.…”

We determine the sensitivity to neutrino oscillation parameters from a study of atmospheric neutrinos in a magnetised detector such as the ICAL at the proposed India-based Neutrino Observatory. In such a detector, which can separately count ν μ and ν μ -induced events, the relatively smaller (about 5%) uncertainties on the neutrinoantineutrino flux ratios translate to a constraint in the χ 2 analysis that results in a significant improvement in the precision with which neutrino oscillation parameters such as sin 2 θ 23 can be determined. Such an effect is unique to all magnetisable detectors and constitutes a great advantage in determining neutrino oscillation parameters using such detectors. Such a study has been performed for the first time here. Along with an increase in the kinematic range compared to earlier analyses, this results in sensitivities to oscillation parameters in the 2-3 sector that are comparable to or better than those from accelerator experiments where the fluxes are significantly higher. For example, the 1σ precisions on sin 2 θ 23 and | m 2 32(31) | achievable for 500 kton year exposure of ICAL are ∼9 and ∼2.5%, respectively, for both normal and inverted hierarchies. The mass hierarchy sensitivity achievable with this combination when the true hierarchy is normal (inverted) for the same exposure is χ 2 ≈ 8.5 ( χ 2 ≈ 9.5).
