Abstract

We report on newest results in \({{k}_{{\text{T}}}}\)-factorization approach for \(ep\)-processes. We describe HERA data on longitudinal structure function measurements as well as on associated prompt photon and jet photoproduction. The calculations include first application of the new LLM-2022 transverse momentum dependent gluon distribution developed by the authors. The study includes also the first implementation of parton showers for photoproduction processes in \({{k}_{{\text{T}}}}\)-factorization. The data are described well with the simulations. The \(ep\)-processes are included to the new version of Monte-Carlo generator pegasus.

外延过程 kT 因子化的新成果

我们报告了({{k}_{text/{T}}}}\)-因子化方法用于\(ep/)-过程的最新成果。我们描述了HERA的纵向结构函数测量数据，以及相关的瞬发光子和射流光生成数据。计算中首次应用了作者开发的新的 LLM-2022 横向动量相关胶子分布。这项研究还包括首次在\({{k}_{\text{T}}}}\)-因子化中实现了光生过程的粒子显影。数据与模拟结果描述吻合。新版本的蒙特卡洛发生器pegasus也包含了\(ep\)-过程。

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
