# The Monte Carlo program LESKO-F for deep inelastic e±p → e± X scattering at HERA including QED bremsstrahlung from the lepton line

## Description

Abstract A Monte Carlo event generator for deep inelastic electron (position) proton neutral current scattering at HERA energies is described. It includes O (α) QED bremsstrahlung from the lepton line and allows for longitudinal polarization of the lepton beam. Final particles are produced on the parton level, i.e. the final state is described by the four-momenta of lepton, quark, photon and proton remnant. Information on each generated event is stored in t... Title of program: LESKO-F version 2.2 Catalogue Id: ACJZ_v1_0 Nature of problem In deep inelastic electron proton scattering the QED radiative corrections, in particular the effects due to bremsstrahlung from the lepton line, are well known, in some regions of the phase space, to be rather big, even of the order of 100 per cent. These effects have to be calculated if we want to extract physically significant information from the experimental data, e.g. for the measurement of the proton structure functions. The QED radiative effects, as it is generally known, depend substant ...
