High precision determination of s from a global fit of jet α rates Article (Published Version) Abstract: We present state-of-the-art extractions of the strong coupling based on N 3 LO+NNLL accurate predictions for the two-jet rate in the Durham clustering algorithm at e + e − collisions, as well as a simultaneous fit of the two-and three-jet rates taking into account correlations between the two observables. The fits are performed on a large range of data sets collected at the LEP and PETRAdoi:10.1063/1.53613 fatcat:wletabegtfgxjfdpufvzsrfqzy
