[Rivet] hepmc analysis - rivet

[Miroslav Myska]

Hi Holger,

thanks a lot!
This is exactly I am going to do
(plus analyse outgoing parton pT)

At the first sight, it is strange to see, why the MPI
vertex has to be 2->2. It can not be 2->1 ?

  if (npin ==  npartin && npout == npartout && npin == 2 && npartin == 
npartout) MPIvertices++;


Thank you both very much,
best wishes
Miro
