Abstract

In this contribution, we summarize and discuss recent theoretical progress on the Standard-Model calculation of joint polarized cross sections of massive multi-boson processes with fully leptonic decays. The topics include fixed-order calculation of higher order QCD and electroweak corrections for both production and decay amplitudes, and parton-shower effects.
