Resumo

A valuable tool used in the search for QCD's critical point is the computation of cumulants of conserved charge. Near this point, it is expected a sharp increase in this quantity due to the divergence of correlation lengths. This calculation requires high statistics, which poses a challenge to hydrodynamics simulations, which tend to be computationally expensive. The issue can be ameliorated by means of a procedure called oversampling, i.e. one repeats the Monte Carlo step of the particlization many times for a single hydro event. However, this has the drawback of removing the effects of fluctuations caused during the particlization. We use a toy model to demonstrate a method to compute cumulants (developed originally by Grassi, Hirayama, and Ollitrault) in a scenario where the oversampling procedure is employed and proceed to compute it for several collision energies.
