Bayesian approach to long-range correlations and multiplicity fluctuations in nucleus-nucleus collisions
read the original abstract
The number of particles detected in a nucleus-nucleus collision strongly depends on the impact parameter of the collision. Therefore, multiplicity fluctuations, as well as rapidity correlations of multiplicities, are dominated by impact parameter fluctuations. We present a method based on Bayesian inference which allows for a robust reconstruction of fluctuations and correlations at fixed impact parameter. We apply the method to ATLAS data on the distribution of charged multiplicity and transverse energy. We argue that multiplicity fluctuations are smaller at large rapidity than around central rapidity. We suggest simple, new analyses, in order to confirm this effect.

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.
