QCD Studies at LEP
Siegfried Bethke (Max Planck Inst. of Physics, Munich, Germany)
TL;DR
This paper reviews experimental studies of Quantum Chromodynamics (QCD) at LEP, including measurements of the strong coupling constant, color factors, jet differences, heavy quark effects, and two-photon processes, confirming key QCD predictions.
Contribution
It provides a comprehensive overview of LEP results that test and validate the non-Abelian gauge structure of QCD and measure fundamental parameters.
Findings
Precise measurements of s at LEP.
Verification of QCD color factor ratios.
Observation of differences between quark and gluon jets.
Abstract
Studies of hadronic final states of annihilations at LEP are reviewed. The topics included cover hadronic event shapes, measurements of , determinations of QCD colour factors and tests of the non-Abelian gauge structure of QCD, differences between quark and gluon jets, QCD with heavy quarks and selected results of two-photon scattering processes.
