Software to preprocess the CMS 2010 Muon and Electron datasets for the two-lepton/four-lepton analysis example of CMS open data

Software to produce the intermediate data files, derived from the primary datasets, for a simple analysis on Z decays to two leptons and ZZ decays to four leptons, of CMS open data.

Two-lepton/four-lepton analysis example of CMS 2010 open data

Example code for a simple analysis on Z decays to two leptons and ZZ decays to four leptons. Please see below the details on data selection and the generated example plots.

Razor filter and analyzer for SUSY searches

This package is a filter that selects events from the MultiJet primary dataset from the CMS open data release, and computes the razor variables MR and Rsq, used in supersymmetric particle searches. More details on the razor variables can be found in Phys. Rev

Software to extract data in csv format from a CMS primary dataset

This package is a filter that selects events from the Mu primary dataset from the CMS open data release. In particular, the event is selected if (for simplicity) there are precisely two muons in the event and at least one is a global muon. A csv file containing the four-vector information, charge and invariant mass of the two muons is produced.

Software to extract the event display format from the CMS primary dataset

Software to extract the data for the browser-based event display for the CMS Experiment

CMS VM Image, for 2010 CMS open data

The virtual machine image is based on CernVM (cernvm.cern.ch), with Scientific Linux CERN 5 (slc5), which is the environment needed for the CMSSW release to be used with the 2010 CMS open data. Access to the data is through XRootD.

Contextualisation scripts to create the CMS VM Image, for 2010 CMS open data

The scripts provided create the CMS virtual machine image based on CernVM (cernvm.cern.ch), with Scientific Linux CERN 5 (slc5).

Example code to produce the di-muon spectrum from a CMS 2010 primary dataset

This simple analysis example 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.
