Di-vector Boson Production with Jets at the LHC

In this talk we present the first calculation of next-to-leading-order QCD corrections for the production of $W^+W^-$ pairs in association with three jets at the LHC. We show the observed improvement in the dependence of total and differential cross sections on the unphysical renormalization and factorization scales. We study the radiation pattern for configurations associated to vector-boson fusion and the impact that the QCD corrections have on them.
