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…

A Bottom-Up EFT Approach To Superdense Baryonic Matter

Mannque Rho

How to arrive at the densest matter in massive compact stars starting from Walecka's linear - mean-field model is described in a series of arguments anchored on hidden local…

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…

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…

Correlation between particle spectra and elliptic flow

Tribhuban Parida, Rupam Samanta, Jean-Yves Ollitrault

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…

Understanding the correlation between elliptic and triangular flow

Mubarak Alqahtani, Jean-Yves Ollitrault

The relative correlation between the magnitudes of elliptic flow () and triangular flow () has been accurately measured in nucleus-nucleus collisions at the LHC collider.…
