A four-particle correlation approach 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 $\\sqrt{s_\\mathrm{NN}} = 5.02$ 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 Pb-Pb collisions indicate precisely 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 are biased by kinematic-dependent fluctuations of the flow vector direction of at least 23\\% in central collisions. Given the presented results, existing theoretical models should be re-examined to improve our understanding of initial conditions, quark--gluon plasma (QGP) properties, and the dynamic evolution of the created system.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t1","@type":"Dataset","description":"The ratio $v_{2}{2}/v_2[2]$ as a function of $p_{\\rm T}$ in different centrality intervals","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t2","@type":"Dataset","description":"The ratio $v_{3}{2}/v_3[2]$ as a function of $p_{\\rm T}$ in different centrality intervals","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t3","@type":"Dataset","description":"The ratio $v_{4}{2}/v_4[2]$ as a function of $p_{\\rm T}$ in different centrality intervals","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t4","@type":"Dataset","description":"The factorization ratio $r_{2}$ as a function of $p_{\\rm T}^{\\rm a}$ for different $p_{\\rm T}^{\\rm t}$ intervals in 0-5% centrality","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t5","@type":"Dataset","description":"The factorization ratio $r_{2}$ as a function of $p_{\\rm T}^{\\rm a}$ for different $p_{\\rm T}^{\\rm t}$ intervals in 20-30% centrality","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t6","@type":"Dataset","description":"The factorization ratio $r_{2}$ as a function of $p_{\\rm T}^{\\rm a}$ for different $p_{\\rm T}^{\\rm t}$ intervals in 40-50% centrality","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t7","@type":"Dataset","description":"The factorization ratio $r_{2}$ as a function of $p_{\\rm T}^{\\rm a}$ with $0.2 &lt; p_{\\rm T}^{\\rm t} &lt; 0.6$ GeV/$c$...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t8","@type":"Dataset","description":"The factorization ratio $r_{3}$ as a function of $p_{\\rm T}^{\\rm a}$ for different $p_{\\rm T}^{\\rm t}$ intervals in 0-5% centrality","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t9","@type":"Dataset","description":"The factorization ratio $r_{3}$ as a function of $p_{\\rm T}^{\\rm a}$ for different $p_{\\rm T}^{\\rm t}$ intervals in 20-30% centrality","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t10","@type":"Dataset","description":"The factorization ratio $r_{3}$ as a function of $p_{\\rm T}^{\\rm a}$ for different $p_{\\rm T}^{\\rm t}$ intervals in 40-50% centrality","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t11","@type":"Dataset","description":"The flow angle fluctuation $A_{\\rm 2}^{\\rm f}$ as a function of $p_{\\rm T}$ in different centrality intervals","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t12","@type":"Dataset","description":"The flow magnitude fluctuation $M_{\\rm 2}^{\\rm f}$ as a function of $p_{\\rm T}$ in different centrality intervals","name":"Table 12"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t13","@type":"Dataset","description":"Lower limit of flow angle fluctuations as a function of $p_{\\rm T}$ in different centrality intervals","name":"Table 13"},{"@id":"https://doi.org/10.17182/hepdata.158065.v1/t14","@type":"Dataset","description":"Upper limit of flow magnitude fluctuations as a function of $p_{\\rm T}$ in different centrality intervals","name":"Table 14"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2771093?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/158065"}],"inLanguage":"en","name":"Systematic study of flow vector decorrelation in $\\mathbf{\\sqrt{\\textit{s}_{_{\\bf NN}}}=5.02}$ TeV Pb-Pb collisions","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2771093?version=1","version":1}
