Description

Motivated by the possibility of using advances in developing NNLO subtraction schemes to derive representations for building blocks of modern slicing methods, we derive a simple finite representation of the renormalized N-jettiness soft function at NNLO. The number of hard partons N appears as a parameter in the finite remainder. The cancellation of all infra-red and collinear singularities between the bare soft function and its renormalization constant is demonstrated analytically.
