PEPSI — a Monte Carlo generator for polarized leptoproduction

Abstract
We describe PEPSI (Polarized Electron Proton Scattering Interactions), a Monte Carlo program for polarized deep inelastic leptoproduction mediated by electromagnetic interaction, and explain how to use it. The code is a modification of the LEPTO 4.3 Lund Monte Carlo for unpolarized scattering. The hard virtual gamma-parton scattering is generated according to the polarization-dependent QCD cross-section of the first order in α_S . PEPSI requires the standard polarization-independent JETSET ro...

Title of program: PEPSI version 1.1

Nature of problem
Deep inelastic scattering of longitudinally polarized leptons off polarized nucleons or nuclei are the ideal tools to determine the spin distributions of partons inside such targets. Like the momentum distribution determined by unpolarized deep inelastic scattering, the partonic spin distributions contain an important dynamical information which strongly influence our understanding of the nucleon structure, and hence of non-perturbative Quantum Chromodynamics. The surprising result of a recent E ...
