Monte Carlo Approach to Radiative Corrections in Bhabha Scattering
نویسنده
چکیده
A new Monte Carlo model is proposed for radiative corrections to Bhabha scattering by extending QEDPS developed for multi-photon emission in muon pair production in ee annihilation. This is the QED version of the model known as parton shower in QCD. The main difference between muon pair production and Bhabha scattering is that the latter cross section shows the singularity of 1/t. A shower algorithm is constructed on the radiator formalism modified in a suitable form for this singularity. Some results of the model are presented and compared with O(α) corrections.

متن کاملLABSMC: Monte Carlo event generator for large-angle Bhabha scattering
A Monte Carlo event generator is presented. An original algorithm is developed to simulate electron–positron scattering at energies and momentum transferred much more than the electron mass. The first-order electroweak radiative corrections are included completely. Higher order corrections are taken into account by means of electron structure functions.

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...

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...
متن کاملLarge-angle Bhabha Scattering and Luminosity at Daφne
The accurate knowledge of luminosity at ee flavour factories requires the precision calculation of the Bhabha cross section at large scattering angles. In order to achieve a theoretical accuracy at the 0.1% level, the relevant effect of QED radiative corrections is taken into account in the framework of the Parton Shower method, which allows exclusive event generation. On this scheme, a Monte C...
