摘要：
We present several one-parameter families of higher-order field theory models some of which admit explicit kink solutions with an exponential tail while others admit explicit kink solutions with a power-law tail. Various properties of these families of kink solutions are examined in detail. Further, by applying the recent Manton formalism, we provide estimates for the kink-kink (KK) and antikink-kink (AK-K) acceleration and hence the ratio of the corresponding AK-K and KK forces.
