We derive a closed-form expression for the phase shift experienced by ()-dimensional kinks colliding at ultrarelativistic velocities (), valid for arbitrary periodic potentials. Our closed-form expression is the leading-order result of a more general scattering theory of solitary waves described in a related paper [Phys. Rev. D 88, 105024 (2013)PRVDAQ1550-799810.1103/PhysRevD.88.105024]. This theory relies on a small kinematic parameterrather than a small parameter in the Lagrangian. Our analytic results can be directly extracted from the Lagrangian without solving the equation of motion. Based on our closed-form expression, <?format ?>we prove that kink-kink and kink-antikink collisions haveidenticalphase shifts at leading order.
