I will report on recent advances in the calculation of scattering amplitudes in Quantum Chromodynamics, in particular on new mathematical discoveries and techniques that have made it possible to push their calculations to three loops in perturbation theory.

In 1936, Alexandru Proca put forward the idea of a massive photon, as a means to resolve the infinite electromagnetic energy of a point charge in Maxwell's theory. Proca's proposal quickly became and remains the theoretical cornerstone to non-linear optics.

In 2014, Gianmassimo Tasinato and, independently, Lavinia Heisenberg introduced the notion of a generalized massive photon, classically...
