摘要：

We present an analysis of the effects of multiple-photon emission, in the context of Z0 physics at the SLAC Linear Collider and the CERN e+e- collider LEP, on the forward-backward, left-right, and polarized forward-backward asymmetries for e+e-+-+n() and e+e-bb»+n(). We focus on this Z0-physics scenario in the presence of detector cuts. Realistic calculations are carried out with our Monte Carlo based Yennie-Frautschi-Suura event-by-event approach to SU2L×U1 radiative corrections at high energies. We conclude that the multiple-photon effects should be taken into account for high-precision Z0 physics. We find further that, for high-luminosity unpolarized Z0 physics, the bb»+n() final state looks much more promising as a way to measure the respective forward-backward asymmetry when it is compared to +-+n() insofar as radiative corrections are concerned. © 1990 The American Physical Society.
