Physics:Quantum data analysis/Calorimetry
Calorimetry measures particle energy by absorbing particles in detector material and sampling the resulting electromagnetic or hadronic shower. Calorimeters are essential for measuring photons, electrons, jets, missing transverse momentum, and total event energy. In data analysis, calorimeter information must be calibrated, clustered, corrected, and combined with tracking and muon information.[1]
Electromagnetic and hadronic calorimeters
Electromagnetic calorimeters measure showers from electrons and photons, while hadronic calorimeters measure showers from strongly interacting particles. Hadronic response is more complex because invisible energy and shower fluctuations are larger.[1]
Calibration
Calibration corrects for detector response, nonuniformity, material effects, pileup, and energy scale. Control samples such as known resonances, isolated particles, and test-beam data are used to validate the response.[2][3]
Analysis use
Calorimeter clusters contribute to electron, photon, tau, jet, and missing-energy reconstruction. Their resolution and tails often dominate important systematic uncertainties.[4]
