# Kink scattering in hyperbolic models

## TL;DR

This paper investigates kink-antikink collisions in hyperbolic scalar field models of fourth and sixth order, comparing their scattering patterns with polynomial models and analyzing how interaction order influences scattering structures.

## Contribution

It introduces hyperbolic models of fourth and sixth order and compares their scattering behaviors to polynomial models, highlighting differences and similarities.

## Key findings

- Hyperbolic models differ from polynomial $phi^4$ models in kink interactions.
- Increasing interaction order to sixth order results in similar scattering structures.
- Scattering patterns depend on potential characteristics and vibrational modes.

## Abstract

In this work we study kink-antikink and antikink-kink collisions in hyperbolic models of fourth and sixth order. We compared the patterns of scattering with known results from polynomial models of the same order. The hyperbolic models considered here tend to the polynomial $\phi^4$ and $\phi^6$ models in the limit of small values of the scalar field. We show that kinks and antikinks that interact hyperbolically with fourth order differ sensibly from those governed by the polynomial $\phi^4$ model. The increasing of the order of interaction to the sixth order shows that the hyperbolic and polynomial models give intricate structures of scattering that differ only slightly. The dependence on the order of interaction are related to some characteristics of the models such as the potential of perturbations and the number of vibrational modes.
