Title: Bound state inequality for high mass exchanges in a scalar field model
Author: De Leo, S
Rotelli, P
Abstract: Ladder diagrams are relevant for the study of bound states. The condition on the coupling strength for the existence of a bound state has been deduced in a scalar field theory for the case of low mass exchanges. We apply this approach to the case of very high mass exchanges.
