Merging W W and W W + jet with Minlo

We present a simulation program for the production of a pair of W bosons in association with a jet, that can be used in conjunction with general-purpose shower Monte Carlo generators, according to the Powheg method. We have further adapted and implemented the Minlo^′method on top of the NLO calculation underlying our W⁺W⁻+ jet generator. Thus, the resulting simulation achieves NLO accuracy not only for inclusive distributions in W⁺W⁻+ jet production but also W⁺W⁻production, i.e. when the associated jet is not resolved, without the introduction of any unphysical merging scale. This work represents the first extension of the Minlo^′method, in its original form, to the case of a genuine underlying 2 → 2 process, with non-trivial virtual corrections.
