Since these parameters come from independent fits, the ordering reflects the different spectral shapes of the three species rather than a single thermal source with one common temperature. This is consistent with the expectation that lighter particles are more sensitive to hard-scattering contributions. The freeze-out volume decreases monotonically with decreasing multiplicity, reflecting the shrinking collision geometry. The hierarchy Vπ>VK>Vp is suggestive of species-dependent decoupling behavior. Because V is an effective, model-dependent normalization volume and the three species are fitted independently, this ordering should not be interpreted as direct evidence for sequential freeze-out. All derived quantities exhibit consistent mass-dependent ordering and multiplicity trends, showing a smooth transition from a dense, collision-dominated regime (MC-1) in high-multiplicity events to a more dilute system in the highest multiplicity classes. The multiplicity class MC-10 shows deviations from the smooth trends seen in the other classes. These may reflect a growing contribution from hard processes, fit instability, or limited statistics, and we discuss this as an open point rather than as a clear transition. The increase of the Knudsen number in the highest multiplicity class shows that the hydrodynamic description becomes less reliable, although the system is still far from free-streaming. These findings provide critical insights into the microscopic properties of the produced medium and its evolution from small to large systems.]]> https://www.frontiersin.org/articles/10.3389/fphy.2026.1920937 https://www.frontiersin.org/articles/10.3389/fphy.2026.1920937 2026-10-21T00:00:00Z Original Research Sowmiya SelvarajAnand Sreekantan Thampy https://www.frontiersin.org/articles/10.3389/fphy.2026.1992029 https://www.frontiersin.org/articles/10.3389/fphy.2026.1992029 2026-10-21T00:00:00Z Mini Review Yang Li https://www.frontiersin.org/articles/10.3389/fphy.2026.1982647 https://www.frontiersin.org/articles/10.3389/fphy.2026.1982647 2026-10-21T00:00:00Z Original Research Oleg KaminskyEvgeny KirichenkoKonstantin Makarevich https://www.frontiersin.org/articles/10.3389/fphy.2026.1873810 https://www.frontiersin.org/articles/10.3389/fphy.2026.1873810 2026-10-20T00:00:00Z Original Research Chen WeiPing-feng LiuWan-ying Rao https://www.frontiersin.org/articles/10.3389/fphy.2026.1942665 https://www.frontiersin.org/articles/10.3389/fphy.2026.1942665 2026-10-19T00:00:00Z Original Research Shuqi MengTengyu JiangQi Huang https://www.frontiersin.org/articles/10.3389/fphy.2026.1926459 https://www.frontiersin.org/articles/10.3389/fphy.2026.1926459 2026-10-19T00:00:00Z Methods Vladimir BačićMichele GuerriniJannis KrumlandAugusto F.
