Actually my question about lanhep and calchep if you have any help,
As the vertex of the 3 gluons in SM : f^abc, already
found in calchep, I have a new vertex of 2 colored scalars with a gluon
proportional to (f^abc + d^abc), where d^abc is the SU(3) symmetric structure constant.
f^abc defined for lanhep as f_SU3^a^b^c.How d^abc will be defined for lanhep.
