The correlator strength is found to decrease monotonically with increasing produced charged-particle multiplicity measured at mid-rapidity in all three systems.  In Xe--Xe and Pb--Pb collisions, the multiplicity dependence of the correlator deviates significantly from a simple power-law scaling as well as from the predictions of the HIJING and AMPT models. The observed deviation from power-law scaling is expected from transverse radial flow in semicentral to central Xe--Xe and Pb--Pb collisions.  In pp collisions, the correlation strength is also studied by classifying the events based on the transverse spherocity, $S_0$, of the particle production at midrapidity, used as a proxy for the presence of a pronounced back-to-back jet topology. Low-spherocity (jetty) events feature a larger correlation strength than those with high spherocity (isotropic). The strength and multiplicity dependence of jetty and isotropic events are well reproduced by calculations with the PYTHIA 8 and EPOS LHC models.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t1","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }$$/\\langle\\langle p_{\\rm T} \\rangle\\rangle $, as a function...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t2","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }$$/\\langle\\langle p_{\\rm T} \\rangle\\rangle $, as a function...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t3","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }$$/\\langle\\langle p_{\\rm T} \\rangle\\rangle $, as a function...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t4","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }/\\langle\\langle p_{\\rm T} \\rangle\\rangle $, as a function...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t5","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }/\\langle\\langle p_{\\rm T} \\rangle\\rangle $, as a function...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t6","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }/\\langle\\langle p_{\\rm T} \\rangle\\rangle $, as a function...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t7","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }/\\langle\\langle p_{\\rm T} \\rangle\\rangle $ as a function...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t8","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }/\\langle\\langle p_{\\rm T} \\rangle\\rangle $ as a function...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t9","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }/\\langle\\langle p_{\\rm T} \\rangle\\rangle $ as a function...","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t10","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }/\\langle\\langle p_{\\rm T} \\rangle\\rangle $ as a function...","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t11","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }/\\langle\\langle p_{\\rm T} \\rangle\\rangle $ as a function...","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.159277.v1/t12","@type":"Dataset","description":"Normalized transverse momentum correlator, $\\sqrt{ \\langle\\langle \\Delta p_{{\\rm T}1}\\Delta p_{{\\rm T}2} \\rangle\\rangle }/\\langle\\langle p_{\\rm T} \\rangle\\rangle $ as a function...","name":"Table 12"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2848476?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/159277"}],"inLanguage":"en","name":"System size and energy dependence of the mean transverse momentum fluctuations at the LHC","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2848476?version=1","version":1}
