ATLAS H->bb Results

The following documents were produced so far in this group:

Fall 2012:

Summer 2012: Winter 2011: Summer 2011:

Intermediate results and information:

HSG5 SVN area for analysis code

HSG5 SVN area for documentation

Quick instructions to handle note drafts in SVN

One can browse the HSG5 area here with Trac. The HEAD of the code is stored in trunk/ directory. All the various snapshots are stored in the tags/ directory. If commiting/tagging a change to a note or associated code, please consider following these steps:

  • Initial setup: export SVNROOT=svn+ssh://"USERNAME"@svn.cern.ch/reps/atlasphys
    • (e.g.: for user jgoncalo export SVNROOT=svn+ssh://jgoncalo@svn.cern.ch/reps/atlas-jgoncalo )
    • OLD: (e.g.: for user jgoncalo export SVNROOT=svn+ssh://jgoncalo@svn.cern.ch/reps/atlasphys )
  • Setup editor: export SVN_EDITOR="emacs -nw"
  • Check out a 'tagged' version e.g.:
    svn co $SVNROOT/Physics/Higgs/HSG5/data_7TeV/ATL_COM_PHYS_2010_292/tags/ATL_COM_PHYS_2010_292-00-00-XX
  • Make changes to code/note
  • Edit ChangeLog, in emacs CTRL-x 4 a creates blank entry. Ensure new proposed tag is written in to ChangeLog and all Modified/Added files listed. Try to describe your change in words.
  • Check no merge conflicts (C) e.g.: svn status
  • Now make sure you are in the directory where the ChangeLog file is, then switch to the HEAD of the TRUNK (Gets changes from HEAD in trunk/ to local copy):
    svn switch $SVNROOT/Physics/Higgs/HSG5/data_7TeV/ATL-COM-PHYS-2010-292/trunk
  • Re-check no merge conflicts (C) e.g.: e.g.: svn status
    • if any files appear with a 'C' against them you MUST resolve this conflict before proceeding!
  • Commit to SVN e.g.: svn ci -m "See ChangeLog"
  • Tag in SVN:
    svn cp  $SVNROOT/Physics/Higgs/HSG5/data_7TeV/ATL_COM_PHYS_2010_292/trunk $SVNROOT/Physics/Higgs/HSG5/data_7TeV/ATL_COM_PHYS_2010_292/tags/ATL_COM_PHYS_2010_292-XX-YY-ZZ
    • where ZZ at least is a new number.
  • Then, ion the case of a note, the .pdf should then be replaced here in CDS.

Recipes: Looking at rates from older runs:

1. Using WTRP https://atlasop.cern.ch/atlas-point1/wmi/current/WTRP_wmi/

  1. Root macros from Tomasz in lxplus:
$ ~tbold/public/draw_rates.py -p http -a 145981, see also
For example, this command on lxplus will plot b trigger rates:
$ ~tbold/public/draw_rates.py -p http -a 155116 -l
$ ~tbold/public/draw_rates.py -p http -a 155116 -r "L2 L2_b.*output" --smooth=50
  1. Same source, but using TRP for displaying, in lxplus:
~aagaard/public/rateHistory/rateHistory.sh <runnumber>

  1. Last 24 hours including DAQ info in TRP, but only at 1 minute intervals:
pcatr: ~aagaard/ISMirror/rates.sh

  1. Rate predictions and comparisons with online:

  • Status of the online beam position measurement click here and:
    1. Navigate to "HLTPhysicsBeam"
    2. Select "BeamSpot" or "PerBunchInfo"
      • The first gives basic distributions like the cut flow of the algorithm, number of vertices per event, and X, Y, and Z
      • The second gives the positions and vertex count for each BCID.
  • Role management interface
