DESCRIPTION:For decades\, extracting N-photon amplitudes from effective ac
 tions remained a significant algebraic challenge\, often requiring the eva
 luation of numerous Feynman diagrams and complex Dirac traces. In this tal
 k\, we demonstrate how the Worldline Formalism transforms these 'brute-for
 ce' computations into a streamlined and elegant procedure. Using the one-l
 oop Master Formula\, we show that N-photon amplitudes are generated from a
  single path integral\, bypassing the need for individual diagrams and pro
 viding a non-local representation valid at all energy scales. We illustrat
 e the efficiency of this method through the computation of the low-energy 
 limit\, as well as the specific 2-photon and 4-photon cases.\n\nhttps://in
