We estimate the baryon–photon ratio in the Universe via the leptogenesis scenario in the framework of the minimal seesaw model with a minimally modified bipair neutrino mixing. We assume that one of
Charged Lepton Corrections to Scaling Neutrino Mixing
Assuming Majorana nature of neutrinos, a general expression for the charged lepton corrections to scaling neutrino mixing has been obtained in the context of three flavor neutrino oscillations.
CP violation in bipair neutrino mixing
Abstract There are experimentally determined two best-fit points for the atmospheric neutrino mixing angle θ 23 : sin 2 θ 23 = 0.413 (case A) and sin 2 θ 23 = 0.594 (case B). In the bipair neutrino
The tribimaximal mixing describes the observed solar and atmospheric neutrino mixings; however, it predicts vanishing reactor neutrino mixing angle, which is inconsistent with the observed data. We
Corrections for tribimaximal, bimaximal and democratic neutrino mixing matrices
A bstractIn this work we analyze the corrections to tribimaximal (TBM), bimaximal (BM) and democratic (DC) mixing matrices for explaining large reactor mixing angle θ13 and checking the consistency
Parametrization of Pontecorvo–Maki–Nakagawa–Sakata mixing matrix based on CP-violating bipair neutrino mixing
CP violation in neutrino interactions is described by three phases contained in Pontecorvo–Maki–Nakagawa–Sakata mixing matrix (UPMNS). We argue that the phenomenologically consistent result of the
Consistency of perturbed Tribimaximal, Bimaximal and Democratic mixing with Neutrino mixing data
Abstract We scrutinize corrections to tribimaximal (TBM), bimaximal (BM) and democratic (DC) mixing matrices for explaining recent global fit neutrino mixing data. These corrections are parameterized
Phases of flavor neutrino masses and CP-violation
For flavor neutrino masses MijPDG (i,j=e,μ,τi,j=e,μ,τ) compatible with the phase convention defined by Particle Data Group (PDG), if neutrino mixings are controlled by small corrections to those with
Model independent analysis of Dirac CP violating phase for some well-known mixing scenarios
We present a model-independent analysis of Leptonic CP violation for some well known mixing scenarios. In particular, we considered modified schemes for Bimaximal(BM), Democratic(DC), Hexagonal(HG)

We present a systematic analysis of perturbative Hexagonal (HG) mixing for describing recent global fit neutrino mixing data with normal and inverted hierarchy. The corrections to unperturbed mixing


Tri-bimaximal mixing and the neutrino oscillation data
Abstract Following recent results from the SNO solar neutrino experiment and the K2K long-baseline neutrino experiment, the combined existing data on neutrino oscillations now point strongly to a
Wolfenstein-like parametrization of the neutrino mixing matrix
We show that the 3 x 3 lepton flavour mixing matrix V can be expanded in powers of a Wolfenstein-like parameter Lambda drop \V-mu3\ similar to 1/root2, which measures the strength of flavour
Nearly tri bimaximal neutrino mixing and CP violation
We point out two simple but instructive possibilities to modify the tri-bimaximal neutrino mixing ansatz, such that leptonic CP violation can naturally be incorporated into the resultant scenarios of
Bi-maximal mixing of three neutrinos
Abstract We show that if the solar and atmospheric data are both described by maximal vacuum oscillations at the relevant mass scales then there exists a unique mixing matrix for three neutrino
Lepton Mass Hierarchy and Neutrino Oscillations
Starting from the symmetry of lepton flavor democracy, we propose and discuss a simple pattern for the mass generation and flavor mixing of the charged leptons and neutrinos. The three neutrino
Parametrizing the lepton mixing matrix in terms of charged lepton corrections
We consider a parametrization of the lepton mixing matrix in which the deviations from maximal atmospheric mixing and vanishing reactor mixing are obtained in terms of small corrections from the
A Parametrization for the neutrino mixing matrix
We propose a flexible and model independent parametrization of the neutrino mixing matrix, which takes advantage of the fact that there are up to three small quantities in neutrino mixing
Neutrino mixing from the charged lepton sector with sequential right-handed lepton dominance
Abstract We systematically analyze the possibility that bi-large lepton mixing originates from the charged lepton sector in models with sequential dominance for the right-handed charged leptons. We
Maximal neutrino mixing and maximal CP violation
We propose a phenomenological model of lepton mixing and CP violation based on the flavor democracy of charge leptons and the mass degeneracy of neutrinos. A nearly bi-maximal flavor mixing pattern,
