Fermion-Fermion Bound State Condition for Scalar Exchanges
Stefano De Leo, Pietro Rotelli
The condition for the existence of a bound state between two fermions exchanging massive scalars is derived. For low scalar mass, we reproduce the scalar field model result. The hi…

Bound State Inequality for High Mass Exchanges in a Scalar Field Model
Stefano De Leo, Pietro Rotelli
Ladder diagrams are relevant for the study of bound states. The condition upon the coupling strength for the existence of a bound state has been deduced in a scalar field theory fo…
