Measurement of the strong coupling constant alpha-s from global event shape variables of hadronic Z decays

Conjunt de dades

Descripció

CERN-LEP. Measurement of the strong coupling constant alpha_s from a study of global event-shape variables in e+ e- annihilation hadronic Z0 decay. Data come from 52720 hadronic events obtained in the 1989/90 running with the ALEPH detector. The paper covers thrust, oblateness, C-parameter, heavy jet mass, mass difference and differential jet rates. The final value with the smallest theoretical error comes from the differential two-jet rate measured with the E0 (JADE) clustering algorithm.
