\begin{document}$ p_T $\end{document}) distributions of \begin{document}$ \pi^{\mp} $\end{document}, \begin{document}$ K^{\mp} $\end{document}, p(\begin{document}$ \bar{p} $\end{document}), \begin{document}$ K_s^0 $\end{document}, and Λ in various centrality classes of Pb-Pb collisions at \begin{document}$ \sqrt{s_{NN}} = 2.76 $\end{document} TeV. The experimental spectra were analyzed using the Tsallis non-extensive distribution, from which the effective temperature (T), non-extensive parameter (q), and mean transverse momentum (\begin{document}$ \langle p_T \rangle $\end{document}) were extracted for each particle species and centrality bin. To disentangle thermal and collective effects, the mean kinetic freeze-out temperature (\begin{document}$ \langle T_0 \rangle $\end{document}) was obtained from the intercept of the T versus mass relation, and the average transverse flow velocity (\begin{document}$ \langle \beta_T \rangle $\end{document}) was extracted from the slope of \begin{document}$ \langle p_T \rangle $\end{document} versus mean moving mass for pions, kaons, and protons. The results show that T increases and q decreases with centrality, indicating a hotter and more equilibrated system in central collisions. A clear mass dependence of T supports the presence of a multi-freeze-out scenario, with heavier particles decoupling earlier. Both \begin{document}$ \langle T_0 \rangle $\end{document} and \begin{document}$ \langle \beta_T \rangle $\end{document} arise from peripheral to mid-central collisions before saturating toward central events, which may suggest the onset of collective behavior or changes in freeze-out dynamics. These observations provide new insights into the thermal and dynamical properties of the medium created in heavy-ion collisions at the LHC."> Exploring thermalization and multi-freeze-out effects in Pb-Pb collisions based on Tsallis <i>p<sub>T</sub></i> distributions -
