“…According to the Physics White Paper of the ICAL (INO) Collaboration [366], after 10 years run, INO will be able to identify the correct neutrino mass ordering with a significance larger than 3σ. As the experiments discussed above, the atmospheric neutrino results from INO can also be used to test the presence of new physics beyond the SM, such as CPT-or Lorentz violation [368], sterile neutrinos [369,370], dark matter related studies [371,372], non-standard neutrino interactions [373] or decaying neutrinos [374].…”

The ordering of the neutrino masses is a crucial input for a deep understanding of flavor physics, and its determination may provide the key to establish the relationship among the lepton masses and mixings and their analogous properties in the quark sector. The extraction of the neutrino mass ordering is a data-driven field expected to evolve very rapidly in the next decade. In this review, we both analyze the present status and describe the physics of subsequent prospects. Firstly, the different current available tools to measure the neutrino mass ordering are described. Namely, reactor, long-baseline (accelerator and atmospheric) neutrino beams, laboratory searches for beta and neutrinoless double beta decays and observations of the cosmic background radiation and the large scale structure of the universe are carefully reviewed. Secondly, the results from an up-to-date comprehensive global fit are reported: the Bayesian analysis to the 2018 publicly available oscillation and cosmological data sets provides strong evidence for the normal neutrino mass ordering versus the inverted scenario, with a significance of 3.5 standard deviations. This preference for the normal neutrino mass ordering is mostly due to neutrino oscillation measurements. Finally, we shall also emphasize the future perspectives for unveiling the neutrino mass ordering. In this regard, apart from describing the expectations from the aforementioned probes, we also focus on those arising from alternative and novel methods, as 21 cm cosmology, core-collapse supernova neutrinos and the direct detection of relic neutrinos.10 Here, σ 8 corresponds to the normalization of the matter power spectrum on scales of 8h −1 Mpc, see Equation (13). 11 The thermal SZ thermal effect consists on a spectral distortion on CMB photons which arrive along the line of sight of a cluster.

“…For example, the CPT violation or Lorentz symmetry in the neutrino sector can be probed to a good precision, owing to its energy measurement capability [12]. The passage of magnetic monopoles through the detector may be probed by looking for slowly moving undeflected tracks [13].…”

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.

“…Therefore, parameters governing neutrino and antineutrino oscillation probabilities are considered to be identical. But, there is a possibility that neutrino and antineutrino may behave differently [12,13,14,15,16,17,18]. The survival probability for muon neutrinos at a particular energy E ν and propagation length L is given by P (ν µ → ν µ ) 1 − 4 cos 2 θ 13 sin 2 θ 23 × [1 − cos 2 θ 13 sin 2 θ 23 ] sin 2 ( 1.267|∆m 2 32 |L E ν ).…”

The magnetised Iron Calorimeter detector at the India-based Neutrino Observatory (INO) has a unique feature to identify the neutrinos and antineutrinos on an event by event basis. This feature can be harnessed to detect the differences between the oscillation parameters of neutrinos and antineutrinos independently. In this paper, we analysed Charged Current ν µ and ν µ events under the influence of earth matter effect using three neutrino flavor oscillation framework. If the atmospheric mass-squared differences and mixing parameters for neutrinos are different from antineutrinos, we present the prospects for the experimental observation of these differences in atmospheric ν and ν µ oscillations at INO. We estimate the detector sensitivity to confirm a non-zero difference in the mass-squared splittings (|∆m 2 32 | − |∆m 2 32 |) for neutrinos and antineutrinos.
