Analyzed errors for both s and non-s contributions at different LEP energies.
Assessed the impact on LEP1 physics measurements.
Abstract
The theoretical accuracy of the program TOPAZ0 in the large-angle Bhabha channel is estimated. The physical error associated with the full Bhabha cross section and its forward and backward components separately is given for some event selections and several energy points of interest for LEP1 physics, both for the and non- contributions to the cross section.
