Phenomenological quark-lepton mass relations and neutrino mass estimations
Based on the experimental data and estimations of the charged leptons and quark masses, a close power law with exponent 3/4 has been found, connecting the charged lepton masses and up quarks masses. It has been shown that this approximation is considerably better than any known approach. A similar mass relation has been suggested for the masses of the neutral leptons and down quarks. The latter...
متن کاملQuark and lepton mass textures
We review ideas for explaining the pattern of fermion masses and mixing angles based on a spontaneously broken family symmetry. 1 The form of the quark mass matrices. The fundamental parameters of the Standard Model or its supersymmetric extension that are responsible for fermion masses and mixings are the Yukawa couplings or,equivalently, the fermion mass matrix. Unfortunately we do not have s...
متن کاملLepton and Quark Mass Matrices
We propose a model that all quark and lepton mass matrices have the same zero texture. Namely their (1,1), (1,3) and (3,1) components are zeros. The mass matrices are classified into two types I and II. Type I is consistent with the experimental data in quark sector. For lepton sector, if seesaw mechanism is not used, Type II allows a large νμ-ντ mixing angle. However, severe compatibility with...
متن کاملThe Absolute Neutrino Mass Scale, Neutrino Mass Spectrum, Majorana CP-Violation and Neutrinoless Double-Beta Decay
Assuming 3-ν mixing, massive Majorana neutrinos and neutrinoless double-beta ((ββ)0ν -) decay generated only by the (V −A) charged current weak interaction via the exchange of the three Majorana neutrinos, we briefly review the predictions for the effective Majorana mass || in (ββ)0ν -decay and reanalyse the physics potential of future (ββ)0ν -decay experiments to provide information on the ...
متن کاملDouble Beta Decay and the Absolute Neutrino Mass Scale
The marvelous recent results of neutrino oscillation experiments have given us important information on neutrino mixing. The data of solar neutrino experiments and of the KamLAND long-baseline ν̄e disappearance experiment show νe → νμ ,ντ transitions generated by the squared-mass difference ∆mSUN in one of the two ranges [1] 5.1×10−5 < ∆mSUN < 9.7×10 −5(LMA-I) , 1.2×10−4 < ∆mSUN < 1.9×10 −4(LMA-...
