摘要：

A critical assessment is given of the theoretical uncertainty in the predicted cross-sections for large-angle Bhabha scattering at LEP1, with or without t-channel subtraction. To this end a detailed comparison is presented of the results obtained with the programs ALIBABA and TOPAZO. Differences in the implementation of the radiative corrections and the effect of missing higher-order terms are critically discussed. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
