Correlation between particle spectra and elliptic flow

Abstract
We introduce a new observable to probe the collective nature of the radial expansion of the quark-gluon plasma. This observable, dubbed , represents the correlation of the spectrum with elliptic flow, in the same way as the recently measured represents the correlation of the spectrum with the transverse momentum per particle. The advantage of over is that it is measured using a three-particle cumulant, as opposed to a pair correlation, which significantly reduces the sensitivity to nonflow effects. We predict non-trivial differences between and in semi-central Pb+Pb collisions at the Large Hadron Collider (LHC) on the basis of hydrodynamic simulations. A hint of these differences can be seen in the modification of spectra observed by ALICE in event-shape-engineered events.
