Five W-Boson Amplitude is Equal to Near-Null Decagon / A.V.Belitsky, R.N.Lee, A.I.Onishchenko, [a.o.]. – Text : electronic // Physical Review D. – 2026. – Vol. 113, No. 8. – P. 086003. – URL: https://doi.org/10.1103/5sf8-fhmt. – Bibliogr.: 77.
We study a five-leg scattering amplitude on the special Coulomb branch of planar 𝒩=4 super Yang-Mills theory. We reach this point of the moduli space of scalar vacuum expectation values by considering six-dimensional 𝒩 =(1,1) super Yang-Mills theory and reducing it down to four space-time dimensions with extradimensional momenta being nonvanishing. This branch is characterized by massive external W-bosons and massless internal gluons propagating in loops. We analyze the five W-boson amplitude in the kinematics when their masses are much smaller than all Mandelstam-like invariants. This is what we dub the near mass-shell limit. We perform calculations to two-loop order in ’t Hooft coupling, making use of recent advances in analytic calculations of required Feynman integrals. Our findings confirm exponentiation of infrared logarithms and enable us to conjecture a concise all-order expression for the amplitude in question. We further analyze its duality to the square root of a five-point correlation function of infinitely heavy half-BPS (Bogomol’nyi–Prasad–Sommerfield) operators, known as the decagon. By considering the near-null limit for inter-operators distances, we verify that the two objects coincide. This observation corroborates the novel Coulomb amplitudes/heavy correlator duality previously observed for four W-boson amplitudes and Sudakov form factors.
