论文摘要
在先前的分析中，从5个TEV $ p $ -pb和13 TEV $ P $ -P $ -P $ Collisions开发了针对标识的Hadron（PID）光谱开发了两个组合（软+硬）模型（TCM）。频谱数据通常在其统计不确定性中描述。在模型中，是系数$ z_ {si}（n_s）$和$ z_ {hi}（n_s）$，表示在总软$ \ barρ_s$和硬$ \ barρ_h$ ch $电荷密度和与事件的情况下相当大的$ n_s = n_s =δ的vary中，表示强$ \ barρ_s$和硬质量$ \ barρ_h$ theard $ \ barρ_h$ \ bar。这封信报告说，这些系数与$ n_s $的变化意味着将强子物种从软分子转移到硬组件，越来越多地随喷射产量增加，同时保留了统计模型预测的每个物种的总颗粒数。运输程度与强子质量成正比。
In previous analyses a two-component (soft+hard) model (TCM) was developed for identified-hadron (PID) spectra from 5 TeV $p$-Pb and 13 TeV $p$-$p$ collisions. Spectrum data are generally described within their statistical uncertainties. Within the model are coefficients $z_{si}(n_s)$ and $z_{hi}(n_s)$ that denote the fractions of hadron species $i$ within total soft $\bar ρ_s$ and hard $\bar ρ_h$ charge densities and that vary significantly with event index $n_s = Δη\bar ρ_s$. This letter reports that variation of those coefficients with $n_s$ implies transport of hadron species from soft component to hard component, increasingly with increased jet production, while conserving the total particle number for each species that is predicted by a statistical model. The extent of transport is simply proportional to hadron mass.
