A small library of matrix elements obtained with MADGRAPH is included with the standard VINCIA release, along with the corresponding HELAS routines. The interface allows VINCIA to match to these matrix elements during the shower evolution. Currently, we are in the process of migrating from an interface that was based on MG4 to one based on MG5, hence this version of VINCIA only has very limited matrix-element capabilities.
The MG5 matrix elements included with VINCIA are
located in the interfaces/mg5cxx-new and
interfaces/mg5cxx-old subdirectories.
