A Phenomenological Study on Lepton Mass Matrix Textures
نویسندگان
چکیده
The three active light neutrinos are used to explain the neutrino oscillations. The inherently bi-large mixing neutrino mass matrix and the Fritzsch type, bi-small mixing charged lepton mass matrix are assumed. By requiring the maximal νμ − ντ mixing for the atmospheric neutrino problem and the masssquared difference approperiate for the almost maximal mixing solution to the solar neutrino problem, the following quantities are predicted: the νe−νμ mixing, Ve3, CP violation in neutrino oscillations, and the effective electronneutrino mass relevant to neutrinoless double beta decays.

Texture Zeros and Cp-violating Phases in the Neutrino Mass Matrix
We stress that specific texture zeros of lepton mass matrices, which might dynamically arise from a new kind of flavor symmetry, can help us to establish simple and testable relations between the lepton flavor mixing parameters and lepton mass ratios. We present a brief review of one-zero, two-zero and three-zero textures of the neutrino mass matrix. Their phenomenological consequences on neutr...
متن کاملTexture Zeros and Majorana Phases of the Neutrino Mass Matrix
We present the generic formulas to calculate the ratios of neutrino masses and the Majorana phases of CP violation from the neutrino mass matrix with two independent vanishing entries in the flavor basis where the charged lepton mass matrix is diagonal. An order-of-magnitude illustration is given for seven experimentally acceptable textures of the neutrino mass matrix, and some analytical appro...

We show that it is possible to fully determine the neutrino mass spectrum from two-zero textures of the neutrino mass matrix. As a consequence, definite predictions can be obtained for the neutrinoless double beta decay.

متن کاملPhenomenological Analysis of Hybrid Textures of Neutrinos
We present a comprehensive phenomenological analysis of the allowed hybrid textures of neutrinos. Out of a total of sixty hybrid textures with one equality between the elements of neutrino mass matrix and one texture zero only twenty three are found to be viable at 99% C.L. whereas the earlier analysis found fifty four to be viable. We examine the phenomenological implications of the allowed hy...
