CMS masterclass files

Input files for the CMS masterclass (from 2024) as part of the IPPOG International Masterclasses.

The data are selected events detected and reconstructed by the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at CERN. The events were produced in proton-proton collisions during Run 1 of the LHC. 

Each zip file is denoted by a number N which is the approximate size masterclass appropriate for these files. For example, N5 will have 5 separate datasets, suitable for a masterclass of 5-10 students. The datasets are a mix of 1-lepton, 2-lepton, and 4-lepton events. The .ig files are event display files used in the iSpy WebGL event display. The .csv files give kinematic and parent particle information for the input events.
