Description
In ultrarelativistic heavy-ion collisions, the Quark–Gluon Plasma (QGP) is formed, and the study of anisotropic flow serves as a key tool to probe its properties in detail. While the flow of light and strange hadrons reflects the collectivity developed during the partonic stage, resonance particles can experience additional effects during the hadronic phase due to interactions of their decay daughters. These hadronic interactions may modify the observed flow patterns, especially at low transverse momentum, where rescattering processes are dominant. Previous ALICE measurements have shown that the relative yield of $\mathrm{K^\pm(892)}$ to $\mathrm{K}$ decreases with increasing particle multiplicity in heavy-ion collisions, suggesting significant hadronic-phase effects. By comparing the flow coefficients of resonance and stable particles, we can investigate how hadronic interactions influence the collective motion of the system. Such a study provides valuable insight into the influence of hadronic phase on elliptic flow measurements. This poster presents an analysis of the rescattering effects on $\mathrm{K^\pm(892)}$ in the hadronic phase by measuring its anisotropic flow coefficients and comparing them to those of longer-lived particles in Pb–Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.36$ TeV, using data collected with the ALICE detector.
