QCD measurements at the highest LEP2 energies
The upgrade of the LEP centre-of-mass energy up to more than 200 GeV in 1999-2000 offers the interesting possibility to test the Standard Model in this new energy regime.

Sumario: | The upgrade of the LEP centre-of-mass energy up to more than 200 GeV in 1999-2000 offers the interesting possibility to test the Standard Model in this new energy regime. In this report, a brief summary is given of some recent QCD measurements concerning the general properties of multihadronic events produced in e/sup +/e/sup -/ annihilations at LEP2 The topics include event-shapes measurements, determinations of alpha /sub s/, measurements of jet production rates, charged particle momentum spectra and charged hadron multiplicity. Selected results from the four LEP experiments will be presented and discussed. (28 refs). |
