"Collision energy dependence of moments of net-kaon multiplicity distributions at RHIC." <i>Physics Letters B,</i> 785, (2018) Elsevier: 551-560. https://doi.org/10.1016/j.physletb.2018.07.066.https://hdl.handle.net/1911/103515Fluctuations of conserved quantities such as baryon number, charge, and strangeness are sensitive to the correlation length of the hot and dense matter created in relativistic heavy-ion collisions and can be used to search for the QCD critical point. We report the first measurements of the moments of net-kaon multiplicity distributions in Au+Au collisions at sNN=7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, and 200 GeV. The collision centrality and energy dependence of the mean (M), variance (σ2), skewness (S), and kurtosis (κ) for net-kaon multiplicity distributions as well as the ratio σ2/M and the products Sσ and κσ2 are presented. Comparisons are made with Poisson and negative binomial baseline calculations as well as with UrQMD, a transport model (UrQMD) that does not include effects from the QCD critical point. Within current uncertainties, the net-kaon cumulant ratios appear to be monotonic as a function of collision energy.engThis is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/).Journal articlehttps://doi.org/10.1016/j.physletb.2018.07.066
