    Description

    CERN-LEP. Determination of ALPHA-S from the measurment of 18 collinear- andinfrared- safe shape distributions as a function of the polar ange (THETA) of t he THRUST axis w.r.t. the E+ E- beam direction. The jet cone energy fraction (JCEF), defined by the integral of the energy within a conical shell of opening angle CHI about the thrust axis, gives the smallest theoretical and experimental uncertainty, and is used separately to determine ALPHA-S. The numerical values of the distributions are taken from the DELPHI report(PHYS-0827). This part gives the final ALPHA-S values together with the event shape distributions integrated over all THETA.

This part gives the Energy Energy Correlation and it Asymmetry and the JetCone Enegy Fraction in 8 ranges of THETA.

This part gives the distributions of the differential two jet rates in a variety of different jet schemes, as a function of the jet separation parameter YCUT, in 8 THETA ranges.
