A derived class with information read from PYTHIA 8 itself, for output.
|
virtual |
Routine for doing the job of reading and setting info on next event.
Read in event information from PYTHIA 8.
Read process information from Info class, and store it. Note: renormalization scale here, factorization further down. For now always convert to process 9999, instead of infoPtr->code().
Read in particle info one by one, excluding zero and beams, and store it. Note unusual C++ loop range, to better reflect LHA/Fortran standard.
Convert from PYTHIA8 to LHA status codes.
Extract hard-process initiator information from Info class, and store it.
Also extract pdf information from Info class, and store it.
Extract parton shower scales from for DPS processes.
Done.
Implements LHAup.

LHAupFromPYTHIA8 class.
Read in initialization information from PYTHIA 8.
Read in beam from Info class. Parton density left empty.
Currently only one allowed strategy.
Only one process with dummy information. (Can overwrite at the end.)
Done.
Implements LHAup.
| bool updateSigma | ( | ) |
Update cross-section information at the end of the run.
Read out information from PYTHIA 8 and send it in to LHA.
Done.
