The BABAYAGA event generator
The program BABAYAGA is an event generator for QED processes at flavour factories, mainly intended for luminosity measurement of e+e− colliders in the center of mass range 1-10 GeV. Recently, the π+π− channel has been added as well. The relevant (photonic) radiative corrections are simulated by means of a Parton Shower in QED. The theoretical precision of the approach is estimated and some phen...

A new version of the event generator BABAYAGA is presented, which is based on an original matching of the Parton Shower approach with the complete exact O(α) matrix element for the inclusion of the QED radiative corrections to the Bhabha process at flavour factories. The theoretical accuracy of the improved generator is conservatively estimated to be 0.2%, by comparison with independent calcula...
متن کاملMatrix-Element Corrections to Parton Shower Algorithms
We discuss two ways in which parton shower algorithms can be supplemented by matrix-element corrections to ensure the correct hard limit: by using complementary phase-space regions, or by modifying the shower itself. In the former case, existing algorithms are self-consistent only if the total correction is small. In the latter case, existing algorithms are never self-consistent, a problem that...
متن کاملA matrix-element-based modification of the parton shower
The transverse momentum distribution of W bosons at hadron colliders is well described by a parton-shower model for small p⊥ values, but not for large ones. This article is an attempt to give a better description of the distribution by using corrections derived from the matrix-element formalism. The parton shower for qq → W has been modified to resemble the matrix elements of qq → gW and qg → q...
