A method for computing cumulants in relativistic heavy-ion collisions
Résumé
To map QCD phase diagram is one of the greatest challenges for those who study QCD at finite temperature. A class of observables of particular interest in this study are the net-baryon cumulants. However, hydrodynamic-based hybrid models have trouble in computing higher order cumulants due to the high statistics needed. The usual oversampling procedure to increase statistics in such models does not help in this situation because it smears event-by-event fluctuations. We propose a way to compute the cumulants avoiding this issue and show its applications at LHC energies.
