Copenhagen samples for SMP and HIP searches

This page has detailed info on the samples produced for the Copenhagen working meeting Mar 29-31.

Common sample details

All samples contained 10k event at generation step (see below - some Q-ball sim jobs crashed due to G4 bug so some events were lost) and used mc09_7TeV-like settings (r1088):

Release: all steps run under,AtlasProduction
Geometry tag: ATLAS-GEO-08-00-01
Conditions tag: OFLCOND-DR-BS7T-ANom-04

For other details (e.g. preExec etc for in reconstruction), please see AMI tag r1088.

I've made two sets of SYNTs for these samples, one set based on ESD (which contains all the goodies you could imagine, including the InDetLowBetaCandidate variables)

  • These samples (including evgen, HITS and RDO datasets) have been moved to SUSY group space (DESY-HH_PHYS-SUSY).

HIP signal samples:

group10.phys-exotics.ChristianOhm_7TeV_Pythia_Qballs_DrellYan_mXXX_PDG1000QQQ0_CPH2010_15_5_3_12.reco Q-balls of mass XXX GeV (200, 500, 1000, 2000) and electric charge QQQ*e (004, 010, 034, 068, 100) - NB! The release used was really and not, this was a typo from when Frederick moved the samples to exotics group space
user10.ChristianOhm.MC09_900GeV.109999.Pythia_Qballs_Drell-Yan_m200_PDG1000QQQ0.CPH2010. Q-balls of mass 200 GeV and electric charge QQQ*e (004, 010, 034)
  • We have 20 (!) samples @ 7 TeV - all combinations of masses and charges and 3 samples @ 900 GeV.
  • It would be good if these datasets were also replicated to the Exotics group space so that we don't lose them when the scratchdisk is cleaned up...
  • No reliable predictions can be made regarding the production mechanism of Q-balls and magnetic monopoles (their strong EM coupling makes perturbative calculations impossible - can't ignore higher orders!). Therefore, these samples simply use the Drell-Yan process to generate heavy muons, and the PDG code of the heavy muons are then replaced with the PDG code of the Q-balls before the simulation step. This is only done to get $pp$-like kinematics and should not be considered a proper model. In particular should the cross section for this fake process not be used for anything.
  • Unfortunately there is a bug in Geant4 which results in endless looping and/or crashing jobs for heavy particles with large negative electric charges, so many events were lost in the simulation step. When we have started to analyze the ntuples we should fill out this table with the number of surviving events:

Mass q=4e q=10e q=34e q=68e q=100e
200 GeV          
500 GeV          
1000 GeV          
2000 GeV
