In terms of the two-body component for the bound state, the current contains two-body operators. We consider the photon interacting with two bosons and the process of pair creation connected to this interaction, interpreting it as a zero mode contribution to the current and discuss the consequences of this pair creation to the components of currents in the light front. © 2013 American Physical Society.engArtigo10.1103/PhysRevD.88.025036WOS:000322114500004Acesso aberto2-s2.0-848815227312-s2.0-84881522731.pdf7511139477883318
