Abstract
En 中文
The uncertainty in the determination of the Z line-shape parameters coming from the precision of the calculation of the initial-state radiation and initial-final-state interference is 2 X 10(-4) for the total cross section sigma(had)(0) at the Z peak, 0.15 MeV for the Z mass M-Z, and 0.1 MeV for the Z width Gamma(Z). Corrections to initial-final-state interference beyond O(alpha(1)) are discussed. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
