摘要
摘要 本文概述了用于模拟质子-质子对撞的蒙特卡罗(MC)事件发生器,以及基于核素的离子对撞机设施(NICA)能量下强子产生的结果。即,介绍了不同对撞能量下p(\(\bar {p}\))、π±、K±的平均倍率、平均横截面矩和快速性分布。我们还研究了稳定带电粒子的双粒子角相关性。使用PYTHIA、EPOS、SMASH和UrQMD事件发生器模拟的结果与现有数据进行了比较。讨论了所研究的量与 MC 发生器中物理机制的联系。我们建议调整一组参数,以解决观察到的数据与PYTHIA之间的差异。
Performance of Monte Carlo Event Generators of pp Collisions at NICA Energies
This paper presents an overview of Monte Carlo (MC) event generators for simulation of proton-proton collisions along with the results on hadron production at nuclotron-based ion collider facility (NICA) energies. Namely, mean multiplicities, mean transverse momenta, and rapidity distributions of p(\(\bar {p}\)), π±, K± at different collision energies are presented. We also study two-particle angular correlations for stable charged particles. Results of simulations with PYTHIA, EPOS, SMASH, and UrQMD event generators are compared to available data. Connections of studied quantities with physics mechanisms in MC generators are discussed. We suggest a tuned set of parameters to address observed discrepancies between data and PYTHIA.
