Higher-Order Moments of Proton-Number Fluctuations in Au+Au Collisions at 1.23A GeV with HADES — •Melanie Szala for the HADES collaboration — Goethe Universität Frankfurt
Higher-order moments of conserved quantities are predicted to be sensitive to a first order phase transition and especially to a critical point of the QCD phase diagram. Strong fluctuations would indeed modify these moments.
The HADES experiment at GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt measured Au+Au collisions at √sNN = 2.41 GeV in 2012 and thus allows to extend the data taken in the RHIC Beam Energy Scan to lower energies.
In this talk we present investigations of the higher moments of proton and deuteron multiplicity distributions. Our results are compared with published RHIC data.
