Description

In this talk, I will present a calculation of the two-loop mixed QCD-electroweak amplitudes for Z+jet production in proton colliders. I will argue that employing a recently proposed projector method reduces the amount of independent Lorentz tensor structures. I will discuss the numerical evaluation of multi-scale Feynman integrals with the Auxiliary Mass Flow method. Finally, I will mention the Sudakov behaviour at large transverse momentum, as well as potential applications to Dark Matter searches at the LHC.
