چکیده

A parton shower method for the photonic radiative correction is applied to the single W -boson production processes. The energy scale for the evolution of the parton shower is determined so that the correct soft-photon emission is reproduced. Photon spectra radiated from the partons are compared with those from the exact matrix elements, and show a good agreement. Possible errors due to a inappropriate energyscale selection or due to the ambiguity of energy scale determination are also discussed, particularly for the measurements on triple gaugecouplings.

An improved Parton Shower algorithm in QED

An improved QED Parton Shower algorithm to calculate photonic radiative corrections to QED processes at flavour factories is described. We consider the possibility of performing photon generation in order to take into account also the effects due to interference between initial and final state radiation. Comparisons with exact order α results are shown and commented.

Monte Carlo Approach to Radiative Corrections in Bhabha Scattering

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 algo...

Initial-state parton shower kinematics for NLO event generators

We are developing a consistent method to combine tree-level event generators for hadron collision interactions with those including one additional QCD radiation from the initial-state partons, based on the limited leading-log (LLL) subtraction method, aiming at an application to NLO event generators. In this method, a boundary between non-radiative and radiative processes necessarily appears at...

Improved Dglap Theory at the Lhc

We discuss the elements of QED⊗QCD exponentiation and its interplay with shower/ME matching and IR-improved DGLAP theory in precision LHC physics scenarios. Applications to single heavy gauge boson production at hadron colliders are illustrated. Given the approaching turn-on of the LHC, the issue of precision predictions for the effects of multiple gluon and multiple pho-ton radiative processes...

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...
