The data are well described by Bose-Einstein correlation functions stemming from L\u00e9vy-stable source distributions. Using a fine transverse momentum binning, we extract the correlation strength parameter $\\lambda$, the L\u00e9vy index of stability $\\alpha$ and the L\u00e9vy length scale parameter $R$ as a function of average transverse mass of the pair $m_{T}$. We find that the positively and the negatively charged pion pairs yield consistent results, and their correlation functions are represented, within uncertainties, by the same L\u00e9vy-stable source functions. The $\\lambda$($m_{T}$) measurements indicate a decrease of the strength of the correlations at low $m_{T}$. The L\u00e9vy length scale parameter $R$($m_{T}$) decreases with increasing $m_{T}$, following a hydrodynamically predicted type of scaling behavior. The values of the L\u00e9vy index of stability $\\alpha$ are found to be significantly lower than the Gaussian case of $\\alpha$ = 2, but also significantly larger than the conjectured value that may characterize the critical point of a second-order quark-hadron phase transition.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.144180.v1/t1","@type":"Dataset","description":"Example fits of Bose-Einstein correlation functions of (a) $\\pi^{-}\\pi^{-}$ pair with $m_{T}$ between 0.331 and 0.349 GeV/$c^2$ and of (b)...","name":"Figure 3a"},{"@id":"https://doi.org/10.17182/hepdata.144180.v1/t2","@type":"Dataset","description":"Example fits of Bose-Einstein correlation functions of (a) $\\pi^{-}\\pi^{-}$ pair with $m_{T}$ between 0.331 and 0.349 GeV/$c^2$ and of (b)...","name":"Figure 3b"},{"@id":"https://doi.org/10.17182/hepdata.144180.v1/t3","@type":"Dataset","description":"Correlation strength parameter $\\lambda$ versus average $m_T$ of the pair, for 0%-30% centrality collisions.
