Volume effect on the extraction of sound velocity in high-energy nucleus-nucleus collisions
read the original abstract
The determination of the speed of sound in quark-gluon plasma is a crucial aspect of understanding the properties of strongly interacting matter created in relativistic heavy-ion collisions. In this study, we investigate the impact of initial-state fluctuations on the extraction of the speed of sound in a quark-gluon plasma in the ultra-central collisions. By employing the TRENTo model for simulating initial conditions, we demonstrate that these fluctuations lead to sizable volume effect, which in turn corrects the measured values of the sound velocity. With respect to realistic conditions of high-energy heavy-ion experiments, we provide quantitative estimate of these corrections.

Extracting the speed of sound of QCD from transverse momentum fluctuations
From ATLAS data on transverse-momentum fluctuations in ultra-central Pb+Pb collisions, the QGP speed of sound is extracted as 0.496 ± 0.008 at 221 ± 13 MeV, matching lattice QCD.

The size of the quark-gluon plasma in ultracentral collisions: impact of initial density fluctuations on the average transverse momentum
Volume variation with multiplicity in ultracentral collisions is small when total entropy scales with nuclear mass number, as shown by relating it to initial density fluctuation profiles.
