Abstract:

The channel coupling effect is discussed for the two-channel amplitude when the threshold of the second channel is very high. The amplitude is written as the sum of the pure elastic term and the channel coupling term. In the low energy region in the first channel, the channel coupling term can be approximated by the modified Born term of an elementary particle (Z3≠0) or intermediate one (Z3=0) corresponding to the cases whether the pure elastic term of the second channel contains a bound state or not, respectively. It is proposed to classify particles and resonances to three categories according to the dynamical origin of them.
