    initial v3  
    11For particles defined in the model setup as chiral there is mismatch of a factor 2 per incoming chiral particle. The beam set-up seems to be wrong in that case.
     2
     3Finally, it turned out that this is treated correctly in WHIZARD 2 (confirmed by analytic calculation and comparison with CalcHEP. Whizard 1, Sherpa and Madgraph are wrong for processes with Weyl spinors in the initial state).
     4I change this into a task for an update of WHIZARD 1.93.
