Strange Neutrino and a Composite Model for Elementary Particle. I

(Received November 26, 1960)
A composite model of the elementary particle is proposed by taking the stable particles, namely proton, electron, neutrino and strange neutrino (ν'), as the basic particles. The strange neutrino was introduced by mass reversal theory as the β-decay product of Λ-particle. It differs from the usual neutrino by mass parity and carries a unit of strangeness. Two neutrinos are both left-handed two-component Dirac spinors.
This model simplifies the mechanism of interactions very much because the basic particles are limited to the stable ones. It is noted that the charge independent strong interactions uniquely require “vacuum-cloud” which is always attached to the core of the elementary particle. The important role of the vacuum-cloud will be revealed throughout this series of papers I-III.
The interactions observed are empirically classified by the three independent reactions inside the core as follows: (a) The origin of the strong interactions is the reaction P ↔π0 P where π0 is just the symbol for the state PP, (b) the reactions reponsible for the leptonic decays of baryons are only µν↔eν and µν' ↔eν', and (c) the non-leptonic decays of baryons take place through the strangeness non-conserving reaction, ν' ↔π0ν. The complete selection rules for the leptonic events are established. In our model the event Σ+ →N+e+ + ν' is possible, while Sakata's model forbids this. The existence of a new neutral pion π0' belonging to I = 0 is suggested.
