228 f(-p1) + f(-p2) W+(νe(p3),e+(p4)))W+(νm(p5)+(p6)) + f(p7) + f(p8), weak

This process calculable at leading order LO.

228.1 νee+νμμ+-pair production via WBF, processes 228,2281

The weak process (nproc=228) occurs in O(α6), whereas the strong process occurs (nproc=2281) in O(α4αS2). These processes can currently only be calculated at lowest order.
