We derive an explicit formula for the low energy limits of the one-loop, on-shell, massive N-photon amplitudes, for arbitrary N and all helicity assignments, in scalar and spinor QED. The two-loop corrections to the same amplitudes are obtained for up to the ten point case. All photon amplitudes with an odd number of `+' helicities are shown to vanish in this limit to all loop orders.

    hep-ph 2025-08 conditional novelty 3.0 of 10

    The gamma-UPC+MG5_aMC framework is presented as the first automated NLO tool for photon-photon processes in UPCs, reviewed alongside recent fixed-order NLO results and data comparisons.

    hep-ph 2025-07 conditional novelty 3.0 of 10

    Compact worldline 'master formulae' for arbitrary-N photon scattering in strong-field backgrounds are presented, but the derivations are largely deferred to the authors' own prior and companion papers.
