Five legs @ three loops: slightly off-shell dual conformal integrals
Andrei V. Belitsky, Leonid V. Bork, Roman N. Lee +2
We calculate the three-loop master integrals contributing to the three-loop five-point amplitude on the special Coulomb branch of SYM theory. For the genuine pentag…
Five legs @ three loops: N=4 sYM amplitude near mass-shell
Andrei V. Belitsky, Leonid V. Bork, Roman N. Lee +1
We present a three-loop analysis of the scattering amplitude of five nearly massless W-bosons in planar maximally supersymmetric Yang-Mills theory. The basis of the master integral…
Five W-boson amplitude = near-null decagon
A. V. Belitsky, L. V. Bork, R. N. Lee +2
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 v…
Tropical regions of near mass-shell pentabox
A. V. Belitsky, V. A. Smirnov
Coulomb branch amplitudes of maximally supersymmetric Yang-Mills theory display infrared properties different from their conformal counterparts. While the four-leg amplitude is kno…
Off-shell form factor: factorization is violated
A. V. Belitsky, V. A. Smirnov
We study the Sudakov form factor on the Coulomb branch of N=4 sYM, which endows only external states with masses, and implies that the former is off-shell in the traditional sense.…
Collinear bootstrap for N=(1,1) sYM
A. V. Belitsky, V. A. Smirnov
We study the multi-collinear behavior of tree amplitudes in the six-dimensional N = (1,1) super Yang-Mills theory (sYM). A generalized dimensional reduction of the latter yields th…
