“…One may note that this expression of oscillation probability is little bit different from that presented by earlier authors [72] because they have considered the perturbative approach for relatively longer baseline and small sin θ 13 ∼ α. For shorter baseline as presented here, the δ dependence appears to be more and instead of being at the order of α 2 it appears at the order α 3/2 as α sin θ 13 ∼ α 3/2 although the expression is same.…”

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

“…It is not completely satisfactory that the most advanced apparatus for precision measurement of the lepton mixing parameters has to rely on the parameter that cannot be directly measured. In fact, the same attitude is shared by the authors of the pioneering work of neutrino factory analysis [15], in which the accuracy of matter density determination by neutrino factory is estimated. Describing an improved way for the in situ measurement of the earth matter density in neutrino factory is nothing but the goal of this paper.…”

We point out that an accurate in situ determination of the earth matter density ρ is possible in neutrino factory by placing a detector at the magic baseline, L = √ 2π/G F N e where N e denotes electron number density. The accuracy of matter density determination is excellent in a region of relatively large θ 13 with fractional uncertainty δρ/ρ of about 0.43%, 1.3%, and < ∼ 3% at 1σ CL at sin 2 2θ 13 = 0.1, 10 −2 , and 3 × 10 −3 , respectively. At smaller θ 13 the uncertainty depends upon the CP phase δ, but it remains small, 3%-7% in more than 3/4 of the entire region of δ at sin 2 2θ 13 = 10 −4 . The results would allow us to solve the problem of obscured CP violation due to the uncertainty of earth matter density in a wide range of θ 13 and δ. It may provide a test for the geophysical model of the earth, or it may serve as a method for stringent test of the MSW theory of neutrino propagation in matter once an accurate geophysical estimation of the matter density is available.

I review oscillation solutions to the neutrino anomalies and discuss how to account for the required pattern of neutrino masses and mixings from first principles. Unification and low-energy bottom-up approaches are discussed, the latter open up the possibility of testing neutrino mixing at high energy colliders, such as the LHC. Large νe mixing is consistent with Supernova (SN) astrophysics and may serve to probe galactic SN parameters at Cherenkov detectors. I discuss the robustness of the atmospheric neutrino oscillation hypothesis against the presence of Flavor Changing (FC) Non-Standard neutrino Interactions (NSI), generally expected in models of neutrino mass. Atmospheric data strongly constrain FC-NSI in the νµ -ντ channel, while solar data can be explained by FC-NSI in the νe -ντ channel, or, alternatively, by spin flavor precession. I illustrate how a neutrino factory offers a unique way to probe for FC-NSI and argue that a near-site detector is necessary in order to probe for leptonic mixing and CP violation.
