Modern particle-physics experiments are large measurement systems that combine accelerators, detectors, triggers, simulation, reconstruction, calibration, and statistical interpretation. Experiments such as ATLAS, CMS, ALICE, and LHCb use different detector designs to address complementary questions about the Standard Model, heavy-ion matter, flavor physics, and possible new phenomena. Their data analysis is inseparable from detector operation.[1]
General-purpose detectors
ATLAS and CMS are general-purpose detectors built to measure a wide range of final states including leptons, photons, jets, missing momentum, and heavy-flavor signatures. Their layered designs combine tracking, calorimetry, muon systems, and trigger infrastructure.[1][2]
Specialized experiments
LHCb is optimized for heavy-flavor physics and forward production, while ALICE is optimized for heavy-ion collisions and quark-gluon plasma studies. Specialized geometry improves sensitivity to particular physics programs.[3][4]
Analysis environment
Modern experiments rely on collaboration-wide software frameworks, shared calibrations, quality flags, Monte Carlo campaigns, and review procedures. A published measurement is the endpoint of a controlled data-production chain.[5][6]
