Centrality-Dependent Lévy HBT Analysis in sNN=5.02 TeV PbPb Collisions at CMS

The measurement of two-particle Bose-Einstein momentum correlation functions are presented using $\sqrt{s_{_{\text{NN}}}}=5.02$ TeV PbPb collision data, recorded by the CMS experiment in 2018. measured discussed terms L\'evy type source distributions. parameters extracted as transverse mass and centrality. These include strength $\lambda$, stability index $\alpha$, scale parameter $R$. shape, characterized is found to be neither Gaussian nor Cauchy. A hydrodynamic-like scaling $R$ also observed.
