Enhanced hydrodynamic predictions for

Rupam Samanta, Tribhuban Parida, Jean-Yves Ollitrault

We present hydrodynamic predictions for the new observable , which measures the correlation of particle spectra with elliptic flow. We implement a data-driven correcti…

Explaining higher-order correlations between elliptic and triangular flow

Mubarak Alqahtani, Jean-Yves Ollitrault

The ALICE and CMS Collaborations have analyzed a number of cumulants mixing elliptic flow () and triangular flow (), involving up to particles, in Pb+Pb collisions at…

Impact parameter dependence of anisotropic flow: Bayesian reconstruction in ultracentral nucleus-nucleus collisions

Mubarak Alqahtani, Rajeev S. Bhalerao, Giuliano Giacalone +2

Peculiar phenomena have been observed in analyses of anisotropic flow () fluctuations in ultracentral nucleus-nucleus collisions: The fourth-order cumulant of the elliptic flo…

The size of the quark-gluon plasma in ultracentral collisions: impact of initial density fluctuations on the average transverse momentum

Fabian Zhou, Giuliano Giacalone, Jean-Yves Ollitrault

Recent experiments have shown that the mean transverse momentum of outgoing particles increases as a function of the particle multiplicity in ultracentral nucl…

Extracting the speed of sound of QCD from transverse momentum fluctuations

Mubarak Alqahtani, Tribhuban Parida, Jean-Yves Ollitrault

We extract the speed of sound () in the quark-gluon plasma from ATLAS data on the probability distribution of the transverse momentum per particle, , in ultra-central P…

The collectivity of transverse momentum fluctuations

Tribhuban Parida, Rupam Samanta, Jean-Yves Ollitrault

We study the observable , which quantifies the relative change of spectra induced by event-by-event density fluctuations in the medium created in heavy-ion collisio…
