Neutrino Mass Matrix with Approximate Flavor Symmetry
Phenomenological implications of neutrino oscillations implied by recent experimental data on pattern of neutrino mass matrix are diss-cussed. It is shown that it is possible to have a neutrino mass matrix which shows approximate flavor symmetry; the neutrino mass differences arise from flavor violation in off-diagonal Yukawa couplings. Two modest extensions of the standard model, which can emb...

متن کاملNew Quadratic Baryon Mass Relations
By assuming the existence of (quasi)-linear baryon Regge trajectories, we derive new quadratic Gell-Mann–Okubo type baryon mass relations. These relations are used to predict the masses of the charmed baryons absent from the Baryon Summary Table so far, in good agreement with the predictions of many other approaches.
متن کاملFlavor-spin Symmetry and the Tensor Charge∗
Investigations of the spin composition of the nucleon have led to surprising insights, beginning with the revelation that the majority of its spin is carried by quark and gluonic orbital angular momenta and gluon spin rather than by quark helicity. In addition, considerable effort has gone into understanding, predicting and measuring the transversity distribution, h1(x), of the nucleon. 3 Trans...
متن کاملValidity of Flavor Symmetry and Charge Symmetry for Parton Distributions
Recent experimental measurements of the Gottfried Sum Rule, and pp and pD Drell-Yan processes, suggest significant violation of flavor symmetry in the proton sea. This interpretation rests on the assumption of parton charge symmetry. Our model calculations suggest charge symmetry violation [CSV] for parton valence distributions of a few percent. Precision measurements of structure functions in ...
