Description:
<jats:p>We present a novel framework to streamline the calculation of jet and beam functions
to next-to-next-to-leading order (NNLO) in perturbation theory. By exploiting the
infrared behaviour of the collinear splitting functions, we factorise the singularities
with suitable phase-space parametrisations and perform the observable-dependent
integrations numerically. We have implemented our approach in the publicly available
code pySecDec and present first results for sample jet and beam functions.</jats:p>
