Zusammenfassung:A bstract Large logarithmic corrections in s ̂ / p t 2 lead to substantial variations in the perturbative predictions for inclusive W -plus-dijet processes at the Large Hadron Collider. This instability can be cured by summing the leading-logarithmic contributions in s ̂ / p t 2 to all orders in α s . As expected though, leading logarithmic accuracy is insufficient to guarantee a suitable description in regions of phase space away from the high energy limit. We present (i) the first calculation of all partonic channels contributing at next-to-leading logarithmic order in W -boson production in association with at least two jets, and (ii) bin-by-bin matching to next-to-leading fixed-order accuracy. This new perturbative input is implemented in High Energy Jets , and systematically improves the description of available experimental data in regions of phase space which are formally subleading with respect to s ̂ / p t 2 .
