Extending the Minlo method

Summary, in English

Abstract: We consider improving Powheg+Minlo simulations, so as to also render them NLO accurate in the description of observables receiving contributions from events with lower parton multiplicity than present in their underlying NLO calculation. On a conceptual level we follow the strategy of the so-called Minlo′programs. Whereas the existing Minlo′framework requires explicit analytic input from higher order resummation, here we derive an effective numerical approximation to these ingredients, by imposing unitarity. This offers a way of extending the Minlo′method to more complex processes, complementary to the known route which uses explicit computations of high-accuracy resummation inputs. Specifically, we have focused on Higgs-plus-two-jet production (Hjj) and related processes. We also consider how one can cover three units of multiplicity at NLO accuracy, i.e. we consider how the Hjj-Minlo simulation may yield NLO accuracy for inclusive H, Hj and Hjj quantities. We perform a feasibility study assessing the potential of these ideas.
