Qcd at High Energy
After more than 25 years of considerable theoretical and experimental efforts, it appears that QCD is the theory of strong interactions. Ideally, in high-energy QCD one needs one single piece of information from the experiments: the value of αs. Starting from that measured value, every observable can be computed from first principles. In practice this is not feasible, since we don’t know how to...
متن کاملDosimetry at high-energy accelerators
R É S U M É Les problèmes de la dosimetric dans les champs de rayonnements ionisants diffusés autour des accélérateurs de haute énergie sont présentés. Après une courte introduction sur l'historique des grandeurs physiques utilisées pour l'acquisition de l'équivalent de dose, les techniques diverses pour la dosimétrie dans des champs mixtes à haute énergie sont décrites, en commençant par des m...
متن کاملSoft Interactions at High Energy
Soft interactions are not easily disentangled from hard ones. In an operational definition of soft and hard processes one finds that at presently analyzed scales there is an interplay of soft and hard processes. As the scale increases, so does the amount of hard processes. So far, nothing is as soft nor as hard as we would like.
متن کاملFundamental Constants at High Energy
The progress of Particle Physics is closely linked to the progress in the understanding of the fundamental constants, like the finestructure constant, the mass of the electron or nucleon, or the electroweak mixing angle. The relation between the 18 fundamental constants of the Standard Model and the elementary units used in other fields like quantum optics or solid state physics is far from tri...
متن کاملQcd at High Energy (experiments)
Recent measurements of QCD interactions involving large momentum transfers are reviewed. The status of measurements of the strong coupling constant is summarised. Recent developments in the measurement and interpretation of deep inelastic scattering, proton-anti-proton collisions and two-photon processes are discussed. While QCD at next-to-leading order gives a qualitative description of many p...
