Abstract:
We derive a compact representation of the renormalized N -jettiness soft
function that is free of infrared and collinear divergences through next-to-next-to-leading
order in perturbative QCD. The number of hard partons N is a parameter in the formula for
the finite remainder. Cancellation of all infrared and collinear singularities between the bare
soft function and its renormalization matrix in color space is demonstrated analytically.
