Determination of the strong coupling constant at LEP
T. Wengler
Abstract
Multi-hadronic events produced in e+e- collisions provide an excellent laboratory to study QCD, the theory of strong interactions, and in particular to determine the strong coupling parameter alphas and demonstrate its predicted behavior as a function of the energy scale. Determinations of alphas at LEP will be reviewed with emphasis on event shape variables and jet rates in 3-jet and 4-jet events.
