CP-Violation phase analysis via nontrivial correlation of quarks and leptons in 3 + 1 scenario

Abstract

The existence and mysterious nature of sterile neutrinos are revolutionizing physics from the particle level to the cosmological scales. The recent results from the MiniBooNE experiment at Fermi-lab observed far more [Formula: see text] appearance than expected, which have provided a hint about the possible existence of sterile neutrinos. The results, if confirmed in future experiments, will have significant implications for cosmology and astroparticle physics. This will require new neutrino mass models to accommodate these additional degrees of freedom. In respect to that, this work is just an extension of our recent work toward the CP phase analysis of Quark-Lepton Complementarity (QLC) model in a [Formula: see text] scenario. The parametrization of CKM4 and PMNS4 using Monte Carlo Simulation is used to estimate the texture of nontrivial correlation matrix [Formula: see text]. As such, we have successfully investigated the constrained values for sterile neutrino parameters, and also predicted the values for Dirac CP-Violation phase and the CP re-phasing invariant [Formula: see text]. The results obtained are consistent with the data available from various experiments, like No[Formula: see text]A, MINOS, SuperK and IceCube-DeepCore. Furthermore, this analysis would be very important in view of growing sterile neutrino experiments.
