Montecarlo Data

This page contains the link to the Montecarlo data generated with genieHad and processed with geant4. Links to the software necessary to run the simulations are included as well.

Software

GenieHad, slic, jas3 and other software tools are available at the following link:

All software related to lcsim is available at:

Generated events

The events generated with GenieHad are available, in hepevt format, at:

The same events, in stdhep format, are available at:

The filename is indicative of the parameters used in the generation. The format is:

redtop.beamenergy.detector_version.process.runnumber.dataset.hepevt

For example, the file: redtop.1800mev.v41.etagammamumu.10001.hepevt corresponds to:

  • beam energy = 1800 MeV
  • detector version = 4.1
  • process: eta-> gamma mu+ mu-
  • run number= 10001

The following table connects the filename to the  GenieHad generator list used. Refer to GenieHad User’s Guide for more details on the generation procedure. The table is updated while more events are processed.

Geant4 processed events

Most of the events generated with GenieHad have also been processed trough Geant4 using the slic framework. The data are available, in slcio format, at the following links:
