Abstract
We study various properties of topological solitons (kinks) of a field-theoretic model with a polynomial potential of the twelfth degree. This model is remarkable in that it has several topological sectors, in which kinks have different masses. We obtain an asymptotic estimate for the kink–antikink and antikink–kink interaction forces. We also study numerically kink–antikink and antikink–kink collisions and observe a number of interesting phenomena: annihilation of a kink–antikink pair in one topological sector and the production in its place of a pair in another sector; resonance phenomena, escape windows, despite the absence of vibrational modes in the kink excitation spectra.
