2291.1 e-νeμ-νμ-pair production via WBF, processes 229,2291

The weak process (nproc=229) occurs in O(α6), whereas the strong process occurs (nproc=2291) in O(α4αS2). These processes can currently only be calculated at lowest order.

229  f (p1)+ f(p2) → W - (e- (p3),νe(p4)))W +(μ- (p5),νμ(p6)) +f (p7)+ f(p8)[W BF ]
2291 f (p )+ f(p ) → W - (e- (p),ν (p )))W - (μ- (p ),ν (p )) +f (p )+ f(p )[strong]
