426 f(-p1) + f(-p2) → W-(→ e-(p3) + ν(p4)) + b(p5), (1, 2 or 3 jets, 4FNS + 5FNS)

426.1 W + Q production in combined 4FNS/5FNS, processes 421, 426

These processes represent the production of a W boson and one or more jets, at least one of which is a b-quark, calculated by combining the 4- and 5-flavour results of processes 401, 411 (for 421) and 406, 416 (for 426). The selection of the final state is the same as for processes 401 and 406, as described in Section ??. The procedure for combining the two calculations is described in refs. [1, 2].
