CMS Pile-up Simulation

Monte Carlo simulation of pile-up is controlled by the code and configuration files of the package SimGeneral/MixingModule. An input distribution is specified for each set of production samples which is supposed to represent the distribution of the mean number of interactions seen during data-taking. Below you can find more information on how the simulation proceeds:

Worksheets and instructions for schools prepared during the High School Teacher Programme 2016

During the High School Teacher Programme in 2016 at CERN, a working group prepared worksheets and instructions on the use of open data in schools. Different aspects of open data were addressed: visualisation of single events, data analysis in spreadsheets and data analysis in python on jupyter notebooks. These files are the result of the working group and they can be used as inspiration for class room activities.

ATLAS 2012 data Egamma-string sample for 2016 open data release

The ATLAS open data dataset is comprised of real data recorded with the ATLAS detector in 2012 and matching simulated data. The set of real data has an integrated luminosity approximately 1fb^-1 centre-of-mass energy of 8 TeV. Events come from period D of the 2012 data taking of the ATLAS experiment.

ATLAS 2012 data Muons-string sample for 2016 open data release

The ATLAS open data dataset is comprised of real data recorded with the ATLAS detector in 2012 and matching simulated data. The set of real data has an integrated luminosity approximately 1fb^-1 centre-of-mass energy of 8 TeV. Events come from period D of the 2012 data taking of the ATLAS experiment.

Validation code for 2010 Commissioning dataset, based on dimuon mass spectrum

This code for validation and benchmarking of the Commissioning dataset is set up at Research level, i.e. it requires university-student-level programming experience. Minimal acquaintance with Linux and the ROOT analysis package (https://root.cern.ch/) as well as a basic text editor is needed. Note that the code in this category is not meant to be a pedagogical example but is a validation tool

Validation code for 2010 MinimumBias dataset, based on track and vertex spectra

This code for validation and benchmarking of the MinimumBias dataset is set up at Research level, i.e. it requires university-student-level programming experience. Minimal acquaintance with Linux and the ROOT analysis package (https://root.cern.ch/) as well as a basic text editor is needed. Note that the code in this category is not meant to be a pedagogical example but is a validation tool

Datasets derived from the Run2011A SingleElectron, SingleMu, DoubleElectron, and DoubleMu primary datasets

These data were selected from the primary datasets in order to obtain candidate J/psi and Y events, candidate W and Z boson events, and general di-electron and dimuon spectra.

CMS luminosity information, for 2010 CMS open data

The integrated luminosity for validated runs and luminosity sections of the 2010 public data (RunB) is available in the table 2010RunBlumi.txt. (The integrated luminosity for validated runs and luminosity sections of all 2010 p-p data taking is available in 2010lumi.txt.)

In your estimate for the integrated luminosity, check for which runs the trigger you have selected is active and sum the values for those runs. The uncertainty in the luminosity measurement of 2010 data should be considered as 11% (reference CMS PAS EWK-10-004).

CMS luminosity information, for 2011 CMS open data

The integrated luminosity for validated runs and luminosity sections of the 2011 public data (RunA) is available in the table 2011RunAlumi.txt. (The integrated luminosity for validated runs and luminosity sections of all 2011 p-p data taking is available in 2011lumi.txt.)

In your estimate for the integrated luminosity, check for which runs the trigger you have selected is active and sum the values for those runs. The uncertainty in the luminosity measurement of 2011 data should be considered as 2.2% (reference CMS PAS SMP-12-008).

If you are using prescaled triggers, you can find the HLT trigger prescale factors for different run ranges in trigger configuration files listed in this record (under "PrescaleService")
