Forte, A. Levy and G. Ridolfi, this contribution collects some of the technological and scientific highlights of precision physics at LEP, the Large Electron-Positron collider operated, from 1989 to 2000, at the European Laboratory for Particle Physics, CERN.Scientifically, the notion of precision relates to the reproducibility and repeatability of a measurement or a prediction. In practical terms, it relates to the degree of consistency of repeated measurements, i.e. to the spread of such results around their average or mean value. The term precision measurements usually implies that one expects significantly higher precision, i.e. smaller spread, than previous measurements. In absolute terms, the attribute precise is often used for results with precisions below the percent level, but this boundary also depends on the current and commonly accepted level of consistency. For instance, measurements or predictions in the field of Quantum Chromodynamics, the gauge field theory of the strong interaction, are regarded to be precise if they reach precisions of 1% or less, while in Quantum Electrodynamics, “precision” would require levels of at least sub-per-mille to even parts-per-million.MPP-2017-263arXiv:1712.03035oai:cds.cern.ch:26380172019 |
