论文摘要
Na61/Shine是CERN超级质子同步器的实验。实验的主要目标是寻找强烈相互作用物质的临界点以及对解解发作的性质的研究。为了实现这些目标，执行了二维扫描（$ 13A-150A $ GEV/$ C $）和系统大小（$ p $+$ p $，be+be，ar+sc，ar+sc，xe+la，pb+pb）。在碰撞的最后阶段，质子的光谱仅受共鸣衰变和由于质量较大而脱落的影响而微弱的影响。因此，质子的速度分布特别敏感反封码的发作。本文对碰撞能量范围内的质子产生介绍了实验结果，这与解次结构的发作最相关。描述了Na61/Shine测量质子速度光谱的过程，以及合作的最新结果来自$ P $+$ P $，BE+BE和AR+SC。提出的实验结果面临现有数据和模型。
NA61/SHINE is an experiment at the CERN Super Proton Synchrotron. The main goals of the experiment are the search for the critical point of strongly interacting matter and the study of the properties of the onset of deconfinement. To reach these goals, the two-dimensional scan in beam momentum ($13A-150A$ GeV/$c$) and system size ($p$+$p$, Be+Be, Ar+Sc, Xe+La, Pb+Pb) was performed. In the final stage of the collision, the spectra of protons are only weakly affected by the effects of resonance decays and rescattering due to their large mass. Thus, proton rapidity distribution is particularly sensitive to the onset of deconfinement. This article presents experimental results on proton production in the collision energy range, which is most relevant to the onset of deconfinement. The procedure of measuring the proton rapidity spectra by NA61/SHINE is described, as well as Collaboration's recent results from reactions of $p$+$p$, Be+Be and Ar+Sc. Presented experimental results are confronted with existing data and models.
