Texture of a Four–Neutrino Mass Matrix
We propose a simple texture of the neutrino mass matrix with one sterile neutrino along with the three standard ones. It gives maximal mixing angles for νe → νS and νμ → ντ oscillations or vice versa. Thus with only four parameters, this mass matrix can explain the solar neutrino anomaly, atmospheric neutrino anomaly, LSND result and the hot dark matter of the universe, while satisfying all oth...
متن کاملA Full Determination of the Neutrino Mass Spectrum from Two-zero Textures of the Neutrino Mass Matrix
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 کاملThe Majorana Neutrino Mass Matrix with One Texture Zero and One Vanishing Eigenvalue
Possible patterns of the Majorana neutrino mass matrix M with one texture zero and one vanishing eigenvalue are classified and discussed. We find that three one-zero textures of M with m1 = 0 and four one-zero textures of M with m3 = 0 are compatible with current neutrino oscillation data. The implications of these phenomenological ansätze on the neutrino mass spectrum and the neutrinoless doub...
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...
متن کاملToward a Neutrino Mass Matrix
left-handed (two-component) neutrinos νe, νμ, and ντ with the left-handed fields se, sμ, and sτ that are the charge conjugates of the right-handed neutrino fields νre, νrμ, νrτ , i.e., se = −iσ2 ν∗ re = (ν† re2,−ν re1), etc. The six left-handed neutrino fields form a six-vector, N = (νe, νμ, ντ , se, sμ, sτ ). The only mass term available for two left-handed neutrino fields Ni and Nj isMij (Ni1...
