Real and Imaginary Elements of Fermion Mass Matrices
Prompted by the recent better determination of the angles of the unitarity triangle, we re-appraise the problem of finding simple fermion mass textures, possibly linked to some symmetry principle and compatible with grand unification. In particular, the indication that the angle α is close to rectangle turns out to be the crucial ingredient leading us to single out fermion mass textures whose e...
متن کاملSmall Elements in Fermion Mass Matrices and Anomalous Dipole Moments
Assuming the small entries in the mass matrices are produced by fermion-scalar loops, we calculate the anomalous dipole moments of the leptons and quarks. The top quark appears in all the loops as the mass seed. When comparing the results with experimental data, including electric and magnetic dipole moments, and radiative transition rates, we obtain the mass limits which are typically larger t...
متن کاملNew Perspective on Fermion Mass Matrices
It is shown that any n × n Dirac fermion mass matrix may be written as the sum of n states of equal “mass”. However, these states are in general not orthogonal. Thus the texture of any such fermion mass matrix may be understood as the nonzero overlap among these states. The fermions of the standard model of particle interactions, i.e. the quarks and leptons, have definite masses and mix with on...
متن کاملFrom Fermion Mass Matrices to Neutrino Oscillations
We present an ansatz for the quark and lepton mass matrices, derivable from SO(10) type GUTs, which accommodates a heavy (> 92GeV ) top quark and permits large mixings in the νμ ↔ ντ sector (as suggested by the recent Kamiokande and IMB data on the atmospheric neutrinos). The well known asymptotic relations mb = mτ , ms = 1 3mμ and mdms = memμ all hold to a good approximation. Depending on νμ ↔...
متن کاملUnification View of Neutrino Mixing and Fermion Mass Matrices
Assuming three light neutrinos and the seesaw mechanism we present a semiquantitative model of fermion masses based on (SUSY) SU(5) and abelian horizontal charges. A good description of the observed pattern of quark and lepton masses is obtained. For neutrinos we naturally obtain widely split masses and large atmospheric neutrino mixing as a consequence of SU(5)-related asymmetric mass matrices...
