Description
We present an automated framework for the computation of gluon jet functions to next-to-next-to-leading order (NNLO) in perturbation theory. Our formalism builds on the SoftSERVE strategy that is used to isolate the implicit phase-space divergences of the collinear matrix elements, keeping the observable-specific measurement function generic. This separation enables the numerical evaluation of the remaining integrals and provides a flexible tool for high-order calculations of jet observables. We demonstrate the method by obtaining new NNLO results for both unpolarised and polarised gluon jet functions for several event-shape variables.
