These processes represent the production of two W+ bosons in association with two (process 251) or three (process 252) jets. The lowest order at which two positively charged W bosons can be produced is with two jets. This process is only implemented for leptonic decays of the W particles. The calculation is available at LO only. The calculation and code are from ref. [1]. removebr is not implemented and has no effect.
is the default plotting routine.
