Comparisons of Fully Differential Exact Results for O(alpha) Virtual Corrections to Single Hard Bremsstrahlung in e+e- Annihilation at High Energies

摘要

We present comparisons of the fully differential exact virtual correction tothe important single hard bremsstrahlung process in e+e- annihilation at highenergies, which is essential for precision studies of the Standard Model from 1GeV to 1 TeV, as calculated by two completely independent methods and groups.We show that the two sets of results are in excellent agreement.Phenomenological implications are discussed.
