论文摘要
我们通过使用颜色字符串percolation Model（CSPM）中的Alice Collongonation中的LHC Energies在LHC Energies上分析LHC Energies上的铅颗粒横向动量光谱（PB-PB）和Proton-Proton（$ {\ BF PP} $）中的温度提取。从测得的能量密度$ {\ bm \ varepsilon} $和温度t无量纲数量$ {\ bm \ varepsilon/} t^{4} $获得以获得自由程度（DOF），$ {\ bm \ varepsilon}/t^$ π^{2}} $/30。 We observe for the first time a two-step behavior in the increase of DOF, characteristic of deconfinement, above the hadronization temperature at temperature $\sim$ 210 MeV for both Pb-Pb and ${\bf pp}$ collisions and a sudden increase to the ideal gas value of $\sim $ 47 corresponding to three quark flavors in the case of Pb-Pb collisions.
We present the extraction of the temperature by analyzing the charged particle transverse momentum spectra in lead-lead (Pb-Pb) and proton-proton (${\bf pp}$) collisions at LHC energies from the ALICE Collaboration using the Color String Percolation Model (CSPM). From the measured energy density ${\bm \varepsilon}$ and the temperature T the dimensionless quantity ${\bm \varepsilon/}T^{4}$ is obtained to get the degrees of freedom (DOF), ${\bm \varepsilon}/T^{4}$ = DOF ${ π^{2}}$/30. We observe for the first time a two-step behavior in the increase of DOF, characteristic of deconfinement, above the hadronization temperature at temperature $\sim$ 210 MeV for both Pb-Pb and ${\bf pp}$ collisions and a sudden increase to the ideal gas value of $\sim $ 47 corresponding to three quark flavors in the case of Pb-Pb collisions.
