1209.4681 (Alfredo Takashi Suzuki et al.)

Zero Mode Effect Generalization for the Electromagnetic Current in the
Light Front
   [PDF]

Alfredo Takashi Suzuki, Jorge Henrique Sales, Luis Alberto Soriano
We consider in this work the electromagnetic current for a system composed by two charged bosons and show that it has a structure of many bodies even in the impulse approximation, when described in the light front time $x^+$. In terms of the two-body component for the bound state, the current contains two-body operators. We discuss the process of pair creation from the interacting photon and interpret it as a zero mode contribution to the current and its consequences for the components of currents in the light-front.
