Abstract (EN): In this work we consider kink-antikink and antikink-kink collisions in a modified phi(4) model with a false vacuum characterized by a dimensionless parameter E. The usual phi(4) model is recovered for E = 0. We investigate the E << 1 regime where the kink in the presence of false vacuum can be understood as a small deformation of the standard kink for the phi(4) model. We show that the attractive interaction between the kink-antikink pair leads to a rich scattering pattern, in some cases delaying considerably the false vacuum decay.
