Title: Scattering of kinks in a non-polynomial model,
Abstract: We study a model described by a single real scalar field in the
two-dimensional space-time. The model is specified by a potential which is
non-polynomial and supports analytical kink-like solutions that are similar to
the standard kink-like solutions that appear in the $\varphi^4$ model when it
develops spontaneous symmetry breaking. We investigate the kink-antikink
scattering problem in the non-polynomial model numerically and highlight some
specific features, which are not present in the standard case.
