Constructing probability density function of net-proton multiplicity distributions using Pearson curve method

Abstract
The probability density functions of net-proton multiplicity distributions are constructed from the Beam Energy Scan results of the STAR experiment using the Pearson curve method for two different transverse momentum windows. The $6^{th}$ and $8^{th}$ order cumulants of net-proton multiplicity distributions are estimated from the constructed probability density functions. The beam energy dependence of $C_{6}/C_{2}$ and $C_{8}/C_{2}$ are found to be sensitive to the acceptance window. This method provides a unique opportunity to study the O(4) criticality near the chiral crossover transition and estimating the higher-order cumulants. In general, it is useful to determine the probability density function uniquely of a frequency data if the first four cumulants are known.

A unified formalism to study transverse momentum spectra in heavy-ion collision

TL;DR: In this paper, a unified non-extensive statistical approach using the Pearson distribution as a tool to study transverse momentum spectra is introduced, which provides strong insights into the underlying physics of heavy-ion collisions.

The order of the quantum chromodynamics transition predicted by the standard model of particle physics

TL;DR: Finite-size scaling analysis shows that the finite-temperature QCD transition in the hot early Universe was not a real phase transition, but an analytic crossover (involving a rapid change, as opposed to a jump, as the temperature varied).

TL;DR: In this paper, the authors considered the class of asymmetrical frequency curves, where the tendency to deviation on one side of the mean is unequal to the tendency of deviation on the other side.

Energy Dependence of Moments of Net-Proton Multiplicity Distributions at RHIC

L. Adamczyk, +355 more
TL;DR: The beam energy and collision centrality dependence of the mean, standard deviation, skewness, and kurtosis of the net-proton multiplicity distributions in Au+Au collisions and the products of moments are found to be significantly below the Skellam expectation and close to expectations based on independent proton and antiproton production.
