New QCD results from LEP
Abstract
I review recent QCD results from LEP. The emphasis is on results that represent new studies and on puzzling disagreements of theory and experiment. Further results are nevertheless mentioned by reference. The new studies discussed in more detail are the most precise measurement of unbiased gluon jets to date, strong evidence of color coherence in 3-jet events, and an, albeit unsuccessful, search for penta-quarks. As yet unexplained disagreements are observed in photon-photon collisions for high momentum charged particle and single jet production, and for the total cross section of b-quark production.
