Importance of volume corrections on the net-charge distributions at the RHIC BES energies

TL;DR

This paper investigates how volume corrections affect net-charge distribution cumulants at RHIC BES energies, showing that these corrections are essential for accurately interpreting fluctuation data in heavy-ion collisions.

Contribution

It demonstrates that incorporating volume corrections into statistical models significantly improves agreement with experimental net-charge fluctuation data.

Findings

Volume corrections are crucial for accurate fluctuation analysis.

Corrected models align well with STAR data.

Volume effects influence event-by-event multiplicity fluctuations.

Abstract

The paper presents my recent investigations of volume corrections on the cumulant products of net-charge distributions in statistical model, corresponding to the data reported by the STAR collaboration. The corrected statistical expectations, under simple Poisson approximations, can reasonably explain the data measured in experiment. The results indicate that volume corrections play crucial role in event-by-event multiplicity fluctuation studies.
