The data sample, containing $4.27\\times 10^{9}$ events corresponding to an integrated luminosity of 0.607 $\\mathrm{nb}^{-1}$, was collected by the CMS experiment in 2018. The experimental results are discussed in terms of a Levy-type source distribution. The parameters of this distribution are extracted as functions  of particle pair average transverse mass and collision centrality. These parameters include the correlation strength parameter, the Levy index or shape parameter ($\\alpha$), and the Levy scale parameter ($R$). The source shape, characterized by $\\alpha$, is found to be neither Cauchy nor Gaussian, implying the need for a full Levy analysis. Similarly to what was previously found for systems characterized by Gaussian source radii, a hydrodynamical scaling is also observed for the Levy $R$ parameter.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.134676.v1/t1","@type":"Dataset","description":"The correlation function $C_2(q)$ of negatively charged hadron pairs with $1.00<K_{\\mathrm{T}}<1.05$ GeV/$c$ in the 10-20% centrality bin.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.134676.v1/t2","@type":"Dataset","description":"The double-ratio correlation function $DR(q)$ of negatively charged hadron pairs with $1.30<K_{\\mathrm{T}}<1.35$ GeV/$c$ in the 20-30% centrality bin.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.134676.v1/t3","@type":"Dataset","description":"The two-particle correlation function of negatively charged hadron pairs with $0.9<K_{\\mathrm{T}}<1.3$ GeV/$c$ in the 0-100% centrality range, calculated using MC...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.134676.v1/t4","@type":"Dataset","description":"The Levy scale parameter $R$ versus the transverse mass $m_{\\mathrm{T}}$ in different centrality classes for negatively and positively charged hadron...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.134676.v1/t5","@type":"Dataset","description":"The $1/R^2$ distribution vs. transverse mass $m_{\\mathrm{T}}$ in different centrality classes for negatively and positively charged hadron pairs.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.134676.v1/t6","@type":"Dataset","description":"The linear-fit parameter $A$ versus $\\langle N_{\\text{part}}\\rangle$ for positively and negatively charged hadron pairs.
