Title: Indications for a Critical End Point in the Phase Diagram for Hot and Dense Nuclear Matter

Abstract

Here, excitation functions for the Gaussian emission source radii difference ( R out 2 - R side 2 ) obtained from two-pion interferometry measurements in Au+Au ( s N N = 7.7 200 GeV ) and Pb+Pb ( s N N = 2.76 TeV ) collisions are reported on for a broad range of collision centralities. The observed nonmonotonic excitation functions validate the finite-size scaling patterns expected for the deconfinement phase transition and the critical end point (CEP), in the temperature versus baryon chemical potential ( T, μ B ) plane of the nuclear matter phase diagram. A finite-size scaling (FSS) analysis of these data suggests a second order phase transition with the estimates T cep ~ 165 MeV and μ B cep ~95MeV for the location of the critical end point. The critical exponents ( ν0.66 and γ1.2 ) extracted via the same FSS analysis place this CEP in the 3D Ising model universality class.
