论文摘要
将标识的 - hadron（PID）$ p_t $ spectra与13 tev $ p $ - $ p $碰撞的碰撞与两个组件（软+硬）型号（TCM）进行了比较，该模型（TCM）准确地将与Jet相关的强子生产（硬组件）与非jet弹丸 - 烟丝 - 核核苷（软分子）（软分子）进行了区分。目前的$ p $ - $ p $研究与最近对5个TEV $ p $ -pb碰撞的TCM研究的TCM研究相似，并受到指导。这些组合分析有助于建立对小碰撞系统中PID强子产生的精心理解的定量描述，作为对照实验。然后可以将控制与来自更中心A-A碰撞的碰撞数据的常规解释形成对比，以表明形成了夸克 - 杜伦等离子体（QGP）。 PID $ p_t $ spectra从13 tev $ p $ - $ p $ collisions与5 TEV $ P $ -PB碰撞的光谱显示出简单的一致性。强子物种的丰度与大型强子对撞机计划开始之前预测的统计模型趋势一致。差异光谱结构和各种比率度量由TCM定量解释，包括其喷射贡献，并且在小型碰撞系统中没有任何索赔的空间。
Identified-hadron (PID) $p_t$ spectra from 13 TeV $p$-$p$ collisions are compared with a two-component (soft+hard) model (TCM) that accurately distinguishes jet-related hadron production (hard component) from nonjet projectile-nucleon dissociation (soft component). The present $p$-$p$ study is similar to and is guided by recent TCM studies of PID spectra from 5 TeV $p$-Pb collisions. The combined analyses serve to establish a well-understood quantitative description of PID hadron production in small collision systems as a control experiment. The control can then be contrasted with conventional interpretations of collision data from more-central A-A collisions as indicating formation of a quark-gluon plasma (QGP). PID $p_t$ spectra from 13 TeV $p$-$p$ collisions exhibit simple consistency with spectra from 5 TeV $p$-Pb collisions. Hadron species abundances are consistent with statistical-model trends predicted prior to commencement of the large hadron collider program. Differential spectrum structure and various ratio measures are quantitatively explained by the TCM, including its jet contribution, and admit no room for claims of hydrodynamic flows in small collision systems.
