In addition, the recently proposed higher-order correlation between $[p_{\rm T}]$, $v_{\rm 2}$, and $v_{\rm 3}$ is measured for the first time, which shows an anticorrelation for the presented centrality ranges. These measurements are compared with hydrodynamic calculations using IP-Glasma and $\rm T_{R}ENTo$ initial-state shapes, the former based on the Color Glass Condensate effective theory with gluon saturation, and the latter a parameterized model with nucleons as the relevant degrees of freedom. The data are better described by the IP-Glasma rather than the $\rm T_{R}ENTo$ based calculations. In particular, Trajectum and JETSCAPE predictions, both based on the $\rm T_{R}ENTo$ initial state model but with different parameter settings, fail to describe the measurements. As the correlations between $[p_{\rm T}]$ and $v_{\rm n}$ are mainly driven by the correlations of the size and the shape of the system in the initial state, these new studies pave a novel way to characterize the initial state in relativistic heavy-ion collisions. 612 - Cosmic Matter in the Laboratory (POF4-612) G:(DE-HGF)POF4-612 POF4-612 POF IV 0 HGS-HIRe - HGS-HIRe for FAIR (HGS-HIRe) G:(DE-Ds200)HGS-HIRe HGS-HIRe 1 SUC-GSI-Heidelberg - Strategic university cooperation GSI-U Heidelberg (SUC-GSI-HE) G:(DE-Ds200)SUC-GSI-HE SUC-GSI-HE 2 SUC-GSI-Frankfurt - Strategic university cooperation GSI-U Frankfurt/M (SUC-GSI-FR) G:(DE-Ds200)SUC-GSI-FR SUC-GSI-FR 3 SUC-GSI-Darmstadt - Strategic university cooperation GSI-TU Darmstadt (SUC-GSI-DA) G:(DE-Ds200)SUC-GSI-DA SUC-GSI-DA 4 Dataset connected to DataCite LHC LHC: ALICE EXP:(DE-588)4398783-7 EXP:(DE-H253)LHC-Exp-ALICE-20150101 EXP:(DE-H253)LHC-Exp-ALICE-20150101 0 10.17182/HEPDATA.133026 Acharya, Shreyasi et.al.
