| Research Abstract |
The results of research in this period can be clasisficed into the following three.
1) Formulation of the Nambu-Jana-Lasinio model on light-cone and its generalization.
2) Calcation of from factors and structure functions of the mucleon in a relativestic quark model.
3) Completion of a volume of review articles on "Quark cluster model for baryon-baryon interactions
In 1), we have developed a hamiltonian formulation of the Nampu-Jona-Lasinoo (NJL) model on light-come together with Prof. Bentz of Tokai Univ. and pther and generalised the discussion to the problem of deserybong the chiral symmetry and its dynamlcal break down on light-cone in collabaration with Profs. Lenz and Thies of Univ. of Erlangen, Germany and Prof. Ohta of Univ. of Tokyo. A new method of regulanzation has bean proposed.
In 2), we have inclued the axtal diguark corrolation in the relntivistic gaork model of the uncleon based on the NJL model and examdned its effects on static and aynamical orioenties in collabaration with Prof. Bentz, Drs. Ishii and Mineo.
In 3), we have sompleted a volume of Prof. Theor. Phys. Suppl. consisting of review articalrs on "Quark cluster model of baryon-baryon intoraction" together with Profs. Oka and Shimizu and othres.
