Renormalized perturbation theory in an intense background electromagnetic field
Misha A. Lopez-Lopez, Giulio Audagnotto, Antonino Di Piazza
Quantum electrodynamics in strong background electromagnetic fields or strong-field QED (SFQED) has been investigated in great detail at the tree level. The study of SFQED at highe…
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…
Low-energy limit of N-photon amplitudes in a constant field
Naser Ahmadiniaz, Misha A. Lopez-Lopez, Christian Schubert
While the QED photon amplitudes at full momentum so far have been calculated only up to the six-photon level, in the low-energy limit there are explicit formulas for all helicity c…
The QED four-photon amplitudes off-shell: part 2
Naser Ahmadiniaz, Cristhiam Lopez-Arcos, Misha A. Lopez-Lopez +1
This is the second one of a series of four papers devoted to a first calculation of the scalar and spinor QED four-photon amplitudes completely off-shell. We use the worldline form…
The QED four -- photon amplitudes off-shell: part 1
Naser Ahmadiniaz, Cristhiam Lopez-Arcos, Misha A. Lopez-Lopez +1
The QED four-photon amplitude has been well-studied by many authors, and on-shell is treated in many textbooks. However, a calculation with all four photons off-shell is presently…
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…
