abstract
The correlation between the transverse momentum and the azimuthal asymmetry the flow is studied. A correlation coefficient is defined between the average transverse momentum of hadrons emitted in an event and the square of the elliptic or triangular flow coefficient. The hydrodynamic model predicts a positive correlation of the transverse momentum with the elliptic flow, and almost no correlation with the triangular flow in Pb-Pb collisions at LHC energies. In p-Pb collisions the new correlation observable is very sensitive to the mechanism of energy deposition in the first stage of the collision.

Bayesian global fit to Xe-Xe and Pb-Pb LHC data infers nearly maximal triaxiality for the 129Xe ground state and extracts two- and three-particle correlations.
ATLAS measures charged-particle pseudorapidity density and mean transverse momentum in O+O and Ne+Ne collisions at 5.36 TeV as a function of centrality and eta.
Hydrodynamic simulations of heavy-ion collisions demonstrate that cumulants linking mean pT and elliptic flow quantitatively match relations derived from initial-state entropy predictors and moments of harmonic flow.
Factorized sequential Bayesian updates on correlated pseudo-data produce systematic deviations from the joint posterior that increase with correlation strength, while exact conditional-likelihood updates match the joint result; an information decomposition attributes the mismatch to parameter-tuned,
STAR reports energy-dependent variances and covariances of [p_T] and v_n^2 in Au+Au collisions from 14.6 to 200 GeV, with the dimensionless ratio remaining similar across energies.
Rotated PCA of simulated Pb+Pb spectra separates spectral fluctuations into a coherent thermal mode that fully explains v0(pT) and a double-node geometric mode that drives the low-pT sign change of v02(pT).
