Solutions of the Wick-Cutkosky model in the light front dynamics
M. Mangin-Brinet1, J. Carbonell1

We study relativistic effects in a system of two scalar particles interacting via a scalar exchange in the Light Front Dynamcis framework. The results are compared to those provided by Bethe-Salpeter and non relativistic equations. It is found in particular that for massive exchange, the relativistic description is of crucial importance even in the limit of zero binding energy.
