The proton-proton collisions at the LHC are recorded at four locations around the accelerator ring, corresponding to the positions of four gigantic particle detectors – ATLAS, CMS, ALICE and LHCb. The two biggest experiments, ATLAS and CMS, are managed by large teams of experts from around the world, who jointly operate the detector and collect and analyse the data it produces. The INPP HEP group participates in the two general purpose LHC experiments:
