Scattering into the fifth dimension of $$ \mathcal{N} $$ | = 4 super Yang-Mills

We study an alternative to dimensional regularisation of planar scattering amplitudes in$$ \mathcal{N} $$= 4 super Yang-Mills theory by going to the Coulomb phase of the theory. The infrared divergences are regulated by masses obtained from a Higgs mechanism, allowing us to work in four dimensions....
