Abstract
We study the multicollinear behavior of tree amplitudes in the six-dimensional super Yang-Mills theory (sYM). A generalized dimensional reduction of the latter yields the four-dimensional sYM on the Coulomb branch, which is of interest for considerations of massive or off-shell scattering. To this end, we revisit the calculation of tree scattering in the former theory employing the collinear bootstrap and known massless limits. Assuming the universality of the double-collinear asymptotics, the result for six-leg superamplitudes differs from the one available in the literature. We further extract the triple-collinear splitting superamplitudes from these.
