"Automating the calculation of jet and beam functions"
In pertubative QCD large logarithms can arise in the computation of collider observables. These logarithms can be resummed via factorization theorems within Soft-Collinear Effective Theory(SCET). The factorization theorems contain jet and beam functions, which describe the collinear interactions in the final and initial state, respectively.
In this talk I present a systematic framework for the computation of jet and beam functions for generic observables. For this purpose we introduce a phase space parametrisation which allows the factorization of universal singularities of jet and beam functions. We have implemented this framework for different observables, by using the public code "pySecDec" to compute the next-to-next-to-leading order jet and beam functions.
