Abstract Large logarithmic corrections in s ̂ / p t 2 $$ \hat{s}/{p}_t^2 $$ 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 $$ \hat{s}/{p}_t^2 $$ 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 $$ \hat{s}/{p}_t^2 $$ .
