Low-energy limit of N-photon amplitudes in a constant field: Part II
Misha A. Lopez-Lopez
We employ the worldline formalism to derive a series representation of the low-energy limit of the N -photon amplitude in a constant background field for both scalar and spinor QED…

Worldline integration of photon amplitudes
Naser Ahmadiniaz, Victor M. Banda Guzmán, James P. Edwards +5
It has been known for many years that methods inspired by string theory, such as the worldline formalism, allow one to write down integral representations that combine large number…

One-loop vertex correction in a plane wave
A. Di Piazza, M. A. Lopez-Lopez
We compute the general expression of the one-loop vertex correction in an arbitrary plane-wave background field for the case of two on-shell external electrons and an off-shell ext…
