We propose methods to reconstruct particle distributions with and without considering initial volume fluctuations. This approach enables us correct for detector efficiencies fluctuations simultaneously. Our study suggests such a tool could investigate the possible bimodal structure of net-proton distribution in Au+Au collisions at sNN= 7.7 GeV as signature first-order phase transition critical ...

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