These processes represent the production of a W boson which subsequently decays leptonically, in association with a b pair and an additional jet. The effect of the bottom quark mass is neglected throughout and the calculation may be performed at LO only. The corresponding LO processes with a mass for the b-quark are given given in nproc=431,436 and should be used in preference to these processes.
When removebr is true, the W boson does not decay.
nplotter_auto.f is the default plotting routine.
