• 論文の詳細を見る

• Compositeness conditions are investigated in the Green's function approach with particular attention to the self-mass. It is shown that there exist two cases in which the conditions Z_3=0 and Z_3・δμ^2=0 hold. One of them defines the compositeness of a particle, and the other gives the limiting process of Gerstein and Deshpande. The latter process does not lead to the composite solution, but to the intermediate one. The self-mass is found to be indefinite when Z_3=0.
