Abstract
We present the computation of the NLO QCD corrections to the production of a Standard Model Higgs boson in association with up to three jets through gluon-gluon fusion. The computation is performed in the approximation of an infinitely heavy top quark. Before studying some phenomenologically important observables, we describe some technical detail about the computation.

Summary
A major step after the discovery of the Higgs particle [1, 2] is the precise determination of its nature. Root Ntuples Because of the relatively slow NLO computation and the high statistics needed for such a large multiplicity final state, the Monte Carlo events are stored in the form of Root Ntuples They are generated by Sherpa and were first used in the context of vector boson production in association with jets [36]. As can be seen from the ratio plots, the purely dynamical scale choice B leads to flat K-factors, whereas scale choice A shows a decrease of the K-factor with increasing transverse momentum Another interesting question is how observables that are defined independently of a certain jet multiplicity, like the transverse momentum of the Higgs, change under the presence of additional QCD radiation. A theoretical prediction that is based on a merged result of different multiplicities will yield a better description of the data
