Using SLIC for 100 TeV pp

Some reconstructed data are in http://atlaswww.hep.anl.gov/asc/vlhc/data/.

The instruction how to Run SLIC are attached (created by Jan Strube)

For those who have an account at CERN, here are some instructions to go through the different steps of the simulation and reconstruction. We are using Whizard https://whizard.hepforge.org/ to generate the physics eventsŠ

- Setup the environment: source /afs/cern.ch/eng/clic/software/setup.sh
- Download a physics file: wget
ftp://ftp-lcd.slac.stanford.edu/lcd/ILC/ZPole/stdhep/pythia/pythiaZPolemumu
.stdhep
- Download a detector:
-- wget http://lcsim.org/detectors/sidloi3.zip
-- mkdir sidloi3
-- cd sidloi3
-- unzip ../sidloi3.zip
- Convert the compact format to other necessary formats
-- GeomConverter -o lcdd compact.xml sidloi3.lcdd
-- GeomConverter -o heprep compact.xml sidloi3.heprep
-- GeomConverter -o pandora compact.xml sidloi3.pandora
-- cd ..
- Run the simulation on 10 events (The crossing angle of the beams is
flexible in our simulation. The physics is from head-on collisions. The
events need to be boosted appropriately such that the outgoing beams go
through the right beam pipe):
/afs/cern.ch/eng/clic/software/slic/3.0.1/scripts/slic.sh -x -i
pythiaZPolemumu.stdhep -g sidloi3/sidloi3.lcdd -r 10 -m
/afs/cern.ch/user/j/jfstrube/public/FCC/defaultILCCrossingAngle.mac -o
input.slcio
- Run the digitization and tracking:
lcsim -D inputFile=input.slcio -D
trackingStrategies=/afs/cern.ch/user/j/jfstrube/public/FCC/sidloi3_tracking
Strategies.xml -D outputFile=tracking.slcio
/afs/cern.ch/user/j/jfstrube/public/FCC/sid_dbd_prePandora_noOverlay.xml
- Run the particle flow reconstruction:
PandoraFrontend -g sidloi3/sidloi3.pandora -i tracking.slcio -c
/afs/cern.ch/user/j/jfstrube/public/FCC/PandoraSettings_sidloi3.xml

Truth-level Monte Carlo files

Monte Carlo simulation files with 100 TeV collision events can be downloaded from the HepSim repository. You download, view and process Monte Carlo files as explained here. Also, look at the HepSim wiki.
