We investigate the role that quasinormal modes can play in kink-antikink collisions, via an example based on a deformation of the phi(4) model. We find that narrow quasinormal modes can store energy during collision processes and later return it to the translational degrees of freedom. Quasinormal modes also decay, which leads to energy leakage, causing a closing of resonance windows and an increase of the critical velocity. We observe similar phenomena in an effective model, a small modification of the collective-coordinate approach to the phi(4) model. (c) 2018 The Authors. Published by Elsevier B.V.
