Relativistic Quarkonium Model Based on Instantaneous Ladder BS Equation. II -- Mass Levels of Charmonium and Bottonium--

The mass levels of the charm onium and the bottonium are calculated based on the in· stantaneous ladder BS equation. The agreement with experiment is fairly good. We get smaller as than nonrelativistic analyses. !l ms is estimated to be 80 ~ 130Me V. The relativistic effects are not so small in the charm onium.

Phenomenological Model on the Interactions of Elementary Particles, II

Many authors have shown that the universal V-A coupling of the Fermi interaction is not inconsistent with various experimental results. Their assumptions are more or less ad hoc. in this paper, it is shown phenomenologically that the universal V-A coupling is a natural and almost unique consequence of the common character of the interactions belonging to each stratum of interaction strength; especially, a possibility of S-T- P coupling of beta - decay interaction is definitely excluded. To read to this end, one additional assumption is used, setting the relation between a weak bosonfermion interaction and the fundamental interaction. (auth)
