TL;DR: In this paper, the weak and electromagnetic interactions of leptons are examined under the hypothesis that the weak interactions are mediated by vector bosons, and it is shown that the simplest partially-symmetric model reproducing the observed electromagnetic and weak interactions requires the existence of at least four vector-boson fields (including the photon).

TL;DR: In this article, an analysis of leptonic decays based on unitary symmetry for strong interactions and the V-A theory for weak interactions is presented, and an explanation for the observed predominance of the LAMBDA yields + e/sup -/ + nu decay over the lamBDA /sup −/ yields n + e /sup + n decay.
Abstract: An analysis of leptonic decays based on unitary symmetry for strong interactions (eightfold way) and the V-A theory for weak interactions is presented. An explanation for the observed predominance of the LAMBDA yields + e/sup -/ + nu decay over the LAMBDA /sup -/ yields n + e/sup -/ + nu decay is obtained. Branching ratios predicted for electron modes with DELTA S, 1 are presented; the ratios for the above decays agree well with experimental results. (D.C.W.)

TL;DR: In this article, a particle mixture theory of neutrino is proposed assuming the existence of two kinds neutrinos, and a possible unified model of elementary particles is constructed by generalizing the Sakata-Nagoya model, which gives a natural explanation of smallness of leptonic decay rate of hyperons as well as subtle difference of G_ν's between µ-e and β-decay.
Abstract: A particle mixture theory of neutrino is proposed assuming the existence of two kinds of neutrinos. Based on the neutrino-mixture theory, a possible unified model of elementary particles is constructed by generalizing the Sakata-Nagoya model. Our scheme gives a natural explanation of smallness of leptonic decay rate of hyperons as well as the subtle difference of G_ν's between µ-e and β-decay.

TL;DR: In the context of two-flavor neutrino oscillations with CPT invariance, all solutions to the solar neutrinos problem except for the "large mixing angle" region are excluded.
Abstract: KamLAND has measured the flux of ν _e’s from distant nuclear reactors. We find fewer ν _e events than expected from standard assumptions about ν _e propagation at the 99.95% C.L. In a 162 ton·yr exposure the ratio of the observed inverse β-decay events to the expected number without ν _e disappearance is 0.611±0.085(stat)±0.041(syst) for ν _e energies >3.4 MeV. In the context of two-flavor neutrino oscillations with CPT invariance, all solutions to the solar neutrino problem except for the “large mixing angle” region are excluded.
