High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We present the results of our calculations to a one, two, and three loop approximation of the e+^+e^-\rightarrowe+^+e^- Bhabha scattering cross-section at small angles. All terms contributing to the radiatively corrected cross-section, within an accuracy of δσ/σ=0.1%\delta\sigma/ \sigma = 0.1 \% , are explicitely evaluated and presented in an analytic form. O(α)O(\alpha) and O(α2)O(\alpha^2) contributions are kept up to next-to-leading logarithmic accuracy, and O(α3)O(\alpha^3) terms are taken into account to the leading logarithmic approximation. We define an experimentally measurable cross-section by integrating the calculated distributions over a given range of final-state energies and angles. The cross-sections for exclusive channels as well as for the totally integrated distributions are also given.
