Abstract

The study of antiproton yield in \(p\)–\(p\) and \(p\)–\(d\) collisions is important for the astrophysical search for dark matter consisting of Weakly Interacting Massive Particles. Refinement of the production cross section, angular and momentum spectra of produced antiprotons in a wide collision energy range could help to treat the results obtained by the AMS-02 and PAMELA orbit spectrometers. In this paper we present a detailed Monte Carlo study of possible measurements at the planned SPD experiment at the NICA collider that is under construction at JINR (Dubna).

NICA SPD在强子碰撞中反质子产率的研究

摘要

对\（p \） – \（p \）和\（p \） – \（d \）碰撞中反质子产率的研究对于天体搜索弱相互作用的质点组成的暗物质具有重要意义。在宽的碰撞能量范围内细化产生的反质子的产生截面，角度和动量谱可以帮助处理由AMS-02和PAMELA轨道光谱仪获得的结果。在本文中，我们将对正在JINR（杜邦）建造的NICA对撞机计划的SPD实验进行详细的蒙特卡洛研究，以进行可能的测量。
