Correlations between mean transverse momentum [P-T] and anisotropic flow coefficients v(2) or v(3) are measured as a function of centrality in Pb-Pb and Xe-Xe collisions at root(NN)-N-s = 5.02 TeV and 5.44 TeV, respectively, with ALICE. These measurements provide insights into the initial state and help reduce the uncertainty in extracting properties of the quark-gluon plasma in relativistic heavy-ion collisions. The data are better described by the IP-Glasma model than the T(R)ENTo model.
Correlations between mean transverse momentum [P-T] and anisotropic flow coefficients v(2) or v(3) are measured as a function of centrality in Pb-Pb and Xe-Xe collisions at root(NN)-N-s = 5.02 TeV and 5.44 TeV, respectively, with ALICE. In addition, the recently proposed higher-order correlation between [P-T], v(2), and v(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 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 T(R)ENTo based calculations. In particular, Trajectum and JETSCAPE predictions, both based on the T(R)ENTo initial state model but with different parameter settings, fail to describe the measurements. As the correlations between [P-T] and v(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 and help pin down the uncertainty of the extracted properties of the quark-gluon plasma recreated in relativistic heavy-ion collisions.
