Abstract

Antikink-kink (KK) collisions in the ¯ ϕ6 model exhibit resonant scattering although the ϕ6 kinks do not support any bound states to which energy could be transferred. In P. Dorey et al. [Kink-Antikink Collisions in the ϕ6 Model, Phys. Rev. Lett. 107, 091602 (2011)] it was conjectured that, instead, energy is transferred to a collective bound mode of the full KK configuration. Here we present further strong evidence for this ¯ conjecture. Further, we construct a collective coordinate model (CCM) for KK scattering based on this ¯ collective bound mode trapped between the KK pair which allows us to reproduce the full dynamics of ¯ KK¯ scattering with striking accuracy. We also study kink-antikink (KK) scattering and its description by a ¯ CCM. In this case a significant role of radiation is discovered.
