Method of Asymptotic Dynamics in Light-Front Field Theory

We discuss the recently proposed modified approach to asymptotic dynamics in the context of light-front field theories and apply it to light-front quantum electrodynamics (LFQED) and light-front quantum chromodynamics (LFQCD). We show that in the case of LFQED, the improved method leads to the same set of coherent states as the one obtained earlier by us using the standard Kulish and Faddeev (KF) method. However, in the case of LFQCD, the improved method leads to a set of states different from the ones obtained by using the KF method.
