Measurements of the$p_{\mathrm{T}}$-dependent flow vector fluctuations in Pb–Pb collisions at$\sqrt{s_{\mathrm{NN}}}=5.02\mathrm{TeV}$using azimuthal correlations with the ALICE experiment at the Large Hadron Collider are presented. A four-particle correlation approach [ALICE Collaboration, ] is used to quantify the effects of flow angle and magnitude fluctuations separately. This paper extends previous studies to additional centrality intervals and provides measurements of the$p_{\mathrm{T}}$-dependent flow vector fluctuations at$\sqrt{s_{\mathrm{NN}}}=5.02\mathrm{TeV}$with two-particle correlations. Significant$p_{\mathrm{T}}$-dependent fluctuations of the${\vec{V}}_2$flow vector in Pb–Pb collisions are found across different centrality ranges, with the largest fluctuations of up to$\sim 15\%$being present in the 5% most central collisions. In parallel, no evidence of significant$p_{\mathrm{T}}$-dependent fluctuations of${\vec{V}}_3$or${\vec{V}}_4$is found. Additionally, evidence of flow angle and magnitude fluctuations is observed with more than$5\sigma$significance in central collisions. These observations in$\text{Pb–Pb}$collisions indicate where the classical picture of hydrodynamic modeling with a common symmetry plane breaks down. This has implications for hard probes at high$p_{\mathrm{T}}$, which might be biased by$p_{\mathrm{T}}$-dependent flow angle fluctuations of at least 23% in central collisions. Given the presented results, existing theoretical models should be reexamined to improve our understanding of initial conditions, quark–gluon plasma properties, and the dynamic evolution of the created system.
