- Title
Higher Fock Sectors in the Wick-Cutkosky Model.

- Abstract
In the Wick-Cutkosky model we analyze nonperturbatively, in light-front dynamics, the contributions of two-body and higher Fock sectors to the total norm and electromagnetic form factor. It turns out that two- and three-body sectors always dominate. For a maximal value of the coupling constant a = 2p, corresponding to the zero bound-state massM= 0, they contribute 90% to the norm. With decrease of a the two-body contribution increases up to 100%. The form factor asymptotic is always determined by a two-body sector.
