Review of Particle Physics

Continuing the program developed in a previous paper, a "superconductive" solution describing the proton-neutron doublet is obtained from a nonlinear spinor field Lagrangian. We find the pions of finite mass as nucleon-antinucleon bound states by introducing a small bare mass into the Lagrangian which otherwise possesses a certain type of the ${\ensuremath{\gamma}}_{5}$ invariance. In addition, heavier mesons and two-nucleon bound states are obtained in the same approximation. On the basis of numerical mass relations, it is suggested that the bare nucleon field is similar to the electron-neutrino field, and further speculations are made concerning the complete description of the baryons and leptons.

Tri-bimaximal mixing and the neutrino oscillation data

Oscillating neutrinos and μ→ e, γ

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.

Remarks on the unified model of elementary particles

http://inspirehep.net/record/1341897/files/C62-07-04-p663.pdf

By extending the Sakata model, a unified model for elementary particles is proposed, the basic particles in the Sakata model are assumed to be constructed of the lepton and B+, which is regarded as a new kind of matter. The full symmetry among three basic particles and the symmetrical property of the weak interactions which was recently pointed out by Gamba, Marshak and Okubo come automatically of this model. The nature of B+ and the new mechanics which accounts for the binding of B+ to the lepton will be the central problem to be studied in the future. very interesting results which are in good agreement with experimental data. In spite of these successes, the Sakata model has been concerned only with the strongly interacting particles, and nothing has been done with the lepton. TvIoreover, even in the case of strong interactions, the charge independence or the full symmetry (which -we shall call the 1.0.0. symmetry) among the three basic particles was introduced in a formal \vay, and it has not yet been clear why the strong interaction should have such invariance properties. In order to describe both baryon and lepton in a unified way, and to find out a profound meaning hid­ den behind the charge independence or the 1.0.0. symmetry, we must go further from the Sakata model. For this purpose let us turn our attention to the weak interaction. The theory of yveak interaction has now come to a very definite point after the great success of the current-current interaction theory proposed by· Feynman and Cell-Mann. 8 ) Furthermore, it has recently become clear that the Feynman-Gell-Mann current derived from the Sakata model is quite suf--ficient to account for the experimental facts concerning the weak processes. 9 ),10) Especially, it should be noted that the terms which obeyed the conditions J S/ LiQ = - 1 and I LlS/ LlO I > 1 automatically dropped out of the current. Thus, by adopting the Feynman and Cell-Mann theory and

A Unified Model for Elementary Particles

The “fourth” Baryon, Sakata Model and Modified B-L Symmetry. II

A possible unified model for elementary particles is developed by generalizing the viewpoint of Sakata-Nagoya model. Instead of the Sakata triplet (p, nand A), we work with the quartet of new baryons Xo and X CX1, Xz and Xs) of spin 1/2, of which Xo belongs to U(1) whereas the other three to U(3). Strong interactions are subjected to a "broken U(1) X U(3)" symmetry. Baryon octet (N, 1:, A and 3) and meson octets (K, 11:, 71, K; etc.) are interpreted, respectively, as the three (XXXo)­ or two (XX) -body composite systems both belonging to 8-dimensional representations of SU(3). One of the crucial test of the model is the prediction of triplet mesons (XXo), the iso-doublet of which can be identified with /C.-mesons. The baryon quartet, Xo and X, corresponds to four leptons in the sense of "modified" baryon-lepton symmetry. This enables us to explain Cabibbo's pheno­ menological weak interaction as a consequence of the present scheme.
