abstract = {To assess the properties of the quark–gluon
plasma formed in ultrarelativistic ion collisions, the ATLAS
experiment at the LHC measures a correlation between the
mean transverse momentum and the flow harmonics. The
analysis uses data samples of lead–lead and proton–lead collisions
obtained at the centre-of-mass energy per nucleon
pair of 5.02 TeV, corresponding to total integrated luminosities
of 22 μb−1 and 28 nb−1, respectively. The measurement
is performed using a modified Pearson correlation coefficient
with the charged-particle tracks on an event-by-event
basis. The modified Pearson correlation coefficients for the
2nd-, 3rd-, and 4th-order flow harmonics are measured in the
lead–lead collisions as a function of event centrality quantified
as the number of charged particles or the number of
nucleons participating in the collision. Themeasurements are
performed for several intervals of the charged-particle transverse
momentum. The correlation coefficients for all studied
harmonics exhibit a strong centrality evolution, which only
weakly depends on the charged-particle momentum range.
In the proton–lead collisions, the modified Pearson correlation
coefficient measured for the 2nd-order flow harmonics
shows only weak centrality dependence. The lead-lead data
is qualitatively described by the predictions based on the
hydrodynamical model.},
