Symmetry Character of Bound States with Multichannel
Department of Physics, University of Tokyo, Tokyo
(Received March 15, 1965)
It is pointed out from the standpoint of the Green function formalism that the existence of bound states in multichannel problems always introduces a group which is restricted by the degeneracies of bound states and their constituent particles. The vertex function of the secondary interaction between a bound state and its constituent particles is proportional to the Clebsch-Gordan coefficients of the group. Further, it is shown that the bootstrap philosophy can be seen as a formalism in which the elementary (or, more strictly speaking, fundamental) particles and their interactions are eliminated from the usual formalism of the field theory.
