LesHouchesEvents: how to read .lhe file

[CoronaBorealis]

Hello,

I have a .lhe file for the u u > u u interaction and i want to extract the initial and final values of momenta but i don't know how. I could write a c++ program and insert them in arrays but how to exclude all the rest (MG5 Proc card, warnings etc) ?

sorry for any language mistakes

Read in everything in the file and only keep what you want; that's the normal way of doing such things. You might ever be able to find on-line code that already has everything to read the file.

maybe if you search for the LheAnalysis tool in the CERN Twiki it can help you?
