Abstract:
On the basis of previous studies of new particles observed in cosmic ray jets, we make conjecture that newly discovered J or ψ particles are composite particles (p0'p0');p0' denotes a fourth fundamental baryon suggested by a baryon-lepton symmetry model based on four leptons. Further discussion is given for confirmation of the conjecture by means of analysis of mass formula and of decay phenomena of J or ψ particles and some remarks are given for related problems.
