QCD Studies at LEP

Abstract

Studies of hadronic final states of $e^{+}{e}^{-}$ annihilations at LEP are reviewed. The topics included cover hadronic event shapes, measurements of ${\alpha }_s$, 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.
