24. Critical point particle number fluctuations from molecular dynamics

Volodymyr Kuznietsov (Bogolyubov Institute for Theoretical Physics of the National Academy of Sciences of Ukraine)

We study fluctuations of particle number in the presence of a critical point by utilizing molecular dynamics simulations of the classical Lennard-Jones fluid in a periodic box. The numerical solution of the $N$-body problem naturally incorporates all correlations, exact conservation laws, and finite size effects, allowing us to study the fluctuation signatures of the critical point in a...

71. System size dependence of strangeness production from NA61/SHINE

Piotr Podlaski (University of Warsaw (PL))

NA61/SHINE is a multipurpose fixed-target experiment at the CERN Super Proton Synchrotron. The main goals of the NA61/SHINE strong interactions program are to discover the critical point of strongly interacting matter and study the properties of the onset of deconfinement. To reach these goals, hadron production measurements are performed in the form of a two-dimensional scan by varying...

42. Baryon annihilation and multiplicity dependence of p/pi and light nuclei ratios

Volodymyr Vovchenko (Institute for Nuclear Theory, University of Washington)

11/29/22, 5:40 PM

The centrality dependence of the $p/\pi$ ratio measured by the ALICE Collaboration in 5.02 TeV Pb-Pb collisions indicates a statistically significant suppression with the increase of the charged multiplicity, once the centrality-correlated part of the systematic uncertainty is eliminated from the data. We argue that this behavior can be attributed to the presence of baryon annihilation in the...
