摘要:
Hyperorder cumulants C5/C1 and C6/C2 of net -baryon distributions are anticipated to offer crucial insights into the phase transition from quark -gluon plasma to hadronic matter in heavy -ion collisions. However, the accuracy of C5 and C6 is highly contingent on the fine shape of the distribution's tail, the detectable range of which could be essentially truncated by low statistics. In this paper, we use the fast Skellam-based simulations, as well as the ultrarelativistic quantum molecular dynamics model, to assess the impact of limited statistics on the measurements of C5/C1 and C6/C2 of net ...
