dc.description.abstract | We report the measurement of cumulants (Cn,n = 1,...,4) of the net-charge distributions measured within
pseudorapidity (|η| < 0.35) in Au + Au collisions at √sNN = 7.7–200 GeV with the PHENIX experiment at
the Relativistic Heavy Ion Collider. The ratios of cumulants (e.g., C1/C2, C3/C1) of the net-charge distributions,
which can be related to volume independent susceptibility ratios, are studied as a function of centrality and
energy. These quantities are important to understand the quantum-chromodynamics phase diagram and possible
existence of a critical end point. The measured values are very well described by expectation from negative
binomial distributions. We do not observe any nonmonotonic behavior in the ratios of the cumulants as a
function of collision energy. The measured values of C1/C2 and C3/C1 can be directly compared to lattice
quantum-chromodynamics calculations and thus allow extraction of both the chemical freeze-out temperature
and the baryon chemical potential at each center-of-mass energy. The extracted baryon chemical potentials are
in excellent agreement with a thermal-statistical analysis model. | |
