چکیده

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 critically discussed. Research supported by a fellowship of the Royal Dutch Academy of Arts and Sciences.

DFUB 96-21 TP-USL/96/12 April 1997 BHAGEN95: a Monte Carlo program for Bhabha scattering at LEP1/SLC and LEP2 energies

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...

Precision Calculation of Bhabha Scattering at Lep

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...

On Large-Angle Bhabha Scattering at LEP

The theoretical accuracy of the program TOPAZ0 in the large-angle Bhabha channel is estimated. The physical error associated with the full Bhabha cross section and its forward and backward components separately is given for some event selections and several energy points of interest for LEP1 physics, both for the s and non-s contributions to the cross section.

BHWIDE 1.00: O(α) YFS Exponentiated Monte Carlo for Bhabha Scattering at Wide Angles for LEP1/SLC and LEP2†

We present O(α) YFS exponentiated results for wide angle Bhabha scattering at LEP/SLC energies using a new Monte Carlo event generator BHWIDE 1.xx. Our calculations include two options for the pure weak corrections, as presented in Beenakker et al. and in Böhm et al. From comparison with the results of Beenakker et al., Montagna et al. and Cacciari et al., we conclude that the total precision o...

Two-loop QED Corrections to Bhabha Scattering

Bhabha scattering, ee → ee, is a crucial process in the phenomenology of particle physics. Its relevance is mainly due to the fact that it is the process employed to determine the luminosity L at ee colliders: in fact, L = NBhabha/σth, where NBhabha is the rate of Bhabha events and σth is the Bhabha scattering cross section calculated from theory. Two kinematic regions are of special interest f...
