Search for the QCD Critical Point by Higher Moments of Net-proton Multiplicity Distributions at RHIC
Search for the QCD Critical Point by Higher Moments of Net-proton Multiplicity Distributions at RHIC
Higher moments of net-proton multiplicity distributions are applied to search for the QCD critical point. In this paper, we will present measurements for kurtosis ($\kappa$), skewness ($S$) and variance $\sigma^2$) of net-proton multiplicity distributions at the mid-rapidity ($|y|<0.5$) and transverse momentum range $0.4<p_{T}<0.8$ {\gevc} for Au+Au collisions at {\sNN} = …
