Hi Valentin,

Following our discussiong, the issue is not what we discussed.
If you look at diagram #19 (see attachment)
you will see that the following color-flow:
      DATA (ICOLUP(1,I,3,1),I=1, 5)/ 0,503, 0,503, 0/
      DATA (ICOLUP(2,I,3,1),I=1, 5)/501,502, 0,501,502/

is not possible (at minima weird) since the gluon is not connected to the quark with with it interacts. If this should really be consider as LC, then I would need to correct the addmothers function to correct the issue. But sounds an issue on the LC definition here.

Cheers,

Olivier
