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
Catalogue Id: ACJF_v1_0

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 ...

摘要
本文介绍了极化电子质子散射相互作用（Polarized Electron Proton Scattering Interactions，简称PEPSI）——一款用于电磁相互作用介导的极化深度非弹性轻子产生过程的蒙特卡洛（Monte Carlo）程序，并对其使用方法进行了说明。该代码是面向非极化散射的LEPTO 4.3版Lund蒙特卡洛程序的修改版本。硬虚γ-部分子散射过程依据一阶α_S下的极化依赖量子色动力学截面生成。PEPSI需调用标准的非极化依赖JETSET程序例程……

问题描述
纵向极化轻子与极化核子或原子核的深度非弹性散射，是测定此类靶物质内部部分子自旋分布的理想手段。正如非极化深度非弹性散射所测得的动量分布一般，部分子自旋分布蕴含着关键的动力学信息，这将深刻影响我们对核子结构乃至非微扰量子色动力学（Quantum Chromodynamics, QCD）的认知。近期E……的意外观测结果
