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 ? <address> if (npin == npartin && npout == npartout && npin == 2 && npartin == npartout) MPIvertices++;</address> </blockquote> This is at least true for Sherpa where MPI scatters are only modelled as 2->2 scatters. MPI scatters are one of these things where there is no generator independent way of getting these quantities, hence you need to check how to identify MPI scatters in H++.
