论文摘要
proton-proton（$ p $+$ p $），质子 - antiproton（$ p $+$+$+$ \ bar {p} $），proton-n {p} $和proton-lead（$ p $+pb），proton-prop+pb），proton-n = $+pb $+pb），proton-n = 1,2,3 $ $ j/ψ$，$ψ（2s）$和$υ（ns，n = 1,2,3）$ （PB+PB）通过（两个组件）Erlang分布，Hagedorn函数（反向幂律）和TSALLIS-LYVY函数分析了广泛能量范围的碰撞。由于（两个组件）Erlang分布在多源热模型的框架中的拟合，因此从颜色串渗透模型获得了初始温度。某些参数的激发功能，例如平均横向动量和初始温度从数十个GEV升高到10 TEV以上。随着速度的增加（中心性），平均横向动量和初始温度降低（略有变化或明显变化）。同时，$υ（ns，n = 1,2,3）$的平均横向动量大于$ j/ψ$和$ψ$和$ψ（2s）$的平均横向动量，以及$υ（ns，n = 1,2,3）$排放的初始温度高于$ j/ψ$和$ψ$和$ψ$和ψ（2s）$ sissions a Massexents的行为。
The transverse momentum spectra of $J/ψ$, $ψ(2S)$, and $Υ(nS, n=1,2,3)$ produced in proton-proton ($p$+$p$), proton-antiproton ($p$+$\bar{p}$), proton-lead ($p$+Pb), gold-gold (Au+Au), and lead-lead (Pb+Pb) collisions over a wide energy range are analyzed by the (two-component) Erlang distribution, the Hagedorn function (the inverse power-law), and the Tsallis-Levy function. The initial temperature is obtained from the color string percolation model due to the fit by the (two-component) Erlang distribution in the framework of multisource thermal model. The excitation functions of some parameters such as the mean transverse momentum and initial temperature increase from dozens of GeV to above 10 TeV. The mean transverse momentum and initial temperature decrease (increase slightly or do not change obviously) with the increase of rapidity (centrality). Meanwhile, the mean transverse momentum of $Υ(nS, n=1,2,3)$ is larger than that of $J/ψ$ and $ψ(2S)$, and the initial temperature for $Υ(nS, n=1,2,3)$ emission is higher than that for $J/ψ$ and $ψ(2S)$ emission, which shows a mass-dependent behavior.
