We extend to the special case of Bhabha scattering the ”Z-peak subtracted” representation previously applied to e+e− → f f̄ (f 6= e). This allows us to analyze the process at any energy while imposing in an automatic way the constraints set by high precision measurements at the Z peak. The procedure turns out to be particularly convenient for the search of a certain class of new physics effects ...

A program calculating Bhabha scattering at high energy colliders is considered for porting to the EGEE Grid infrastructure. The program code, which is a result of the aitalc project, is ported by using a masterworker operating scheme. The job submission, execution and monitoring are implemented using the GridWay metascheduler. The unattended execution of jobs turned out to be complete and rathe...

For the small-angle Bhabha-scattering process, we consider the error budget for the calculation of the LEP/SLC luminosity in the Monte Carlo event generator BHLUMI 4.04, from the standpoint of new calculations of exact results for the respective O(α 2) photonic corrections in the context of the Yennie-Frautchi-Suura exponentiation. We find that an overall precision tag for the currently availab...

. . 111 The cross section for Bhabha scattering (e+e+ e+c-) with polarized electrons at the center of mass energy of the 2’ resonance has been measured with the SLD experiment at the Stanford Linear Accelerator Center during the 1992 and 1993 runs. The electroweak couplings of the electron are extracted. At small angles the measurement is done in the SLD Silicon/Tungsten Luminosity Monitor (LMS...
