New developments in treacherous points of light-front dynamics

摘要

Light-front dynamics(LFD) plays an important role in hadron phenomenology. The last few years, however, it has been emphasized that treacherous points such as zero-mode contributions should be taken into account for successful LFD applications to hadron phenomenology. We discuss some examples of treacherous points and present new progress made the last few years to handle them correctly. © 2007 Elsevier B.V. All rights reserved.
