“…The optimization of CP violation discovery reach has been done earlier [29,30] for different baselines and different parent muon energy when only SM interactions of neutrinos with matter during propagation is present. We have re-analysed this optimization based on the updated MIND detector characteristics and the migration matrices as given in [44]. We present the result for neutrino factory at 5σ confidence level unlike superbeam case where we have given the results at 3σ confidence level.…”

“…The optimization for CP violation discovery in the context of SM interactions has been done earlier [29,30]. However, in this work we re-analysed this optimization with the updated detector characteristics for the MIND detector [44]. Based on this optimization we have chosen a few relatively shorter baselines (730, 1290 and 1500 kms) and low parent muon energy of 10 GeV.…”

We have studied the CP violation discovery reach in neutrino oscillation experiment with superbeam, neutrino factory and monoenergetic neutrino beam from electron capture process. For NSI satisfying model-dependent bound for shorter baselines (like CERN-Fréjus set-up ) there is insignificant effect of NSI on the the discovery reach of CP violation due to δ. Particularly, for superbeam and neutrino factory we have also considered relatively longer baselines for which there could be significant NSI effects on CP violation discovery reach for higher allowed values of NSI. For monoenergetic beam only shorter baselines are considered to study CP violation with different nuclei as neutrino sources. Interestingly for non-standard interactions -εeµ and εeτ of neutrinos with matter during propagation in longer baselines in superbeam, there is possibility of better discovery reach of CP violation than that with only Standard Model interactions of neutrinos with matter. For complex NSI we have shown the CP violation discovery reach in the plane of Dirac phase δ and NSI phase φij. The CP violation due to some values of δ remain unobservable with present and near future experimental facilities in superbeam and neutrino factory . However, in presence of some ranges of off-diagonal NSI phase values there are some possibilities of discovering total CP violation for any δCP value even at 5σ confidence level for neutrino factory. Our analysis indicates that for some values of NSI phases total CP violation may not be at all observable for any values of δ. Combination of shorter and longer baselines could indicate in some cases the presence of NSI. However, in general for NSIs 1 the CP violation discovery reach is better in neutrino factory set-ups. Using a neutrino beam from electron capture process for nuclei 110 50 Sn and 152 Yb, we have shown the discovery reach of CP violation in neutrino oscillation experiment. Particularly for 110 50 Sn nuclei CP violation could be found for about 51% of the possible δ values for a baseline of 130 km with boost factor γ = 500. The nuclei 152 Yb is although technically more feasible for the production of mono-energetic beam, but is found to be not suitable in obtaining good discovery reach of CP

Abstract. Considering the value of mixing angle θ13 as obtained in recent Daya Bay and MINOS experiments we have explored the discovery reach of CP violation in the leptonic sector due to complex δ phase in neutrino oscillation experiments with superbeam. We have considered two experimental set-up corresponding to two baselines of 130 Km and 2300 Km respectively. Considering numerical simulation we have shown how the discovery reach of CP violation will change due to the presence of various non-standard interactions (NSIs). Although it is known that short baseline is better choice for CP violation study for Standard Model (SM) interactions of neutrinos with matter but in presence of NSI we find that sometimes better discovery reach is possible in relatively longer baselines.
