Three Triplet Model with Double SU(3) Symmetry
With a view to avoiding some of the kinematical and dynamical difficulties involved in the single-triplet quark model, a model for the low-lying baryons and mesons based on three triplets withExpand

Generalization and Interpretation of Dirac's Positive-Energy Relativistic Wave Equation
We generalize Dirac's new equation so as to deacribe particles of mass m and arbitrary spin s. The same remarkable properties are found: positive energy, non-negative density, a conserved four-vectorExpand

Finite quantum electrodynamics: a field theory using an indefinite metric
A finite relativistic field theory of quantum electrodynamics is formulated; the theory involves as an essential element the use of an indefinite metric to remove the divergences. Two auxiliaryExpand

SU2 as a classical invariance group
SummaryThe two-dimensional classical harmonic oscillator and Kepler systems possess integrals of the motion generating the algebra ofSU2. It is shown by explicit classical construction that the onlyExpand

Contribution of Neutral Pions to Photon-Photon Scattering (*).
SummaryIt is shown that the contribution of neutral pion intermediate states is as much important as electron-positron pair states for low energy photon-photon scattering. For unpolarized scatteringExpand

A kinematical model for quarks and hadrons
Starting from simple topological arguments due to Dirac on the classical rotational properties of extended rigid bodies, we abstract the concept of a finite-size spinor (FSS). The FSS is a conceptExpand
