Higher-order Coulomb Corrections to the Threshold e+ e- --> W+ W- Cross Section

Abstract

The QED Coulomb correction is one of the most important corrections to the e+ e- --> W+ W- total cross section near threshold. We calculate these corrections through second order, and discuss the implications for extracting M_W from a threshold cross section measurement at LEP2. Analytic expressions are derived in various kinematic limits.
