Radiative large–angle Bhabha scattering in collinear kinematics
نویسنده
چکیده
The process of large–angle high energy electron–positron scattering with emission of one hard photon almost collinear to one of the charged particles momenta is considered. The differential cross section with radiative corrections due to emission of virtual and soft real photons calculated to a power accuracy is presented. The contribution of two hard photon emission and total expressions for radiative correction are given in leading logarithmical approximation. The latter are illustrated by numeric estimates. A relation of the results with structure function formalism is discussed.

A new Monte Carlo event generator for wide angle Bhabha scattering and muon pair production in e+e− collisions is described. The program includes complete one-loop electroweak corrections, and QED radiative corrections. The O(α) QED correction uses the exact matrix element. Higher order QED corrections are included in an improved soft photon approximation with exponentiation of initial state ra...
متن کاملLarge-Angle Bhabha Scattering at LEP1
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 TOPAZ0. Differences in the implementation of the radiative corrections and the effect of missing higher-order terms are ...
متن کاملThe matrix element for radiative Bhabha scattering in the forward direction
We present an approximation to the matrix element for the process ee → eeγ, appropriate to the situation where one or both of the fermions are scattered over very small angles. The leading terms in the situation where all scattering angles are small contains not only terms quadratic in the electron mass, but also quartic and even sextic terms must be included. Special attention is devoted to th...

We present the Monte Carlo program BHAGEN95, for calculating the crosssection of the Bhabha scattering process at LEP1/SLC and LEP2 energies, usable with continuity from small to large-angle configurations. We discuss some improvements in the event generator BHAGEN94, which is now part of the new code. In particular the weak and QCD corrections are implemented up to two loops for the relevant c...
