Abstract

Abstract We devise a three-point function which describes a process involving transitions between states labeled by four-velocities within an abelian infrared setup. A nonperturbative computation is carried out leading to a form factor which emulates the universal Isgur-Wise function in the heavy-quark effective theory.
