Description
We present a novel formalism to calculate jet functions automatically at next-to-next-to-leading
order in perturbation theory. By employing suitable phase-space parameterisations in combination with
sector-decomposition steps and selector functions, we managed to factorise all divergences in the
phase-space integrations, and we implemented our framework in the publicly available code pySecDec.
Our approach covers a wide class of SCET-1 and SCET-2 observables, and we present results for
several event-shape observables for both quark and gluon jet functions.
