Many recent lattice QCD calculations predict that there may be a first order phase transition from hadronic matter to a Quark-Gluon Plasma that ends in a critical point, with a continuous phase transition on the other side of the critical point. The Relativistic Heavy Ion Collider (RHIC) has conducted a program to probe different regions of the QCD phase diagram in the vicinity of the possible...

In part to search for a possible critical point (CP) in the phase
diagram of hot nuclear matter, a beam energy scan was performed at
the Relativistic Heavy-Ion Collider at Brookhaven National
Laboratory. The STAR experiment collected significant Au+Au data
sets at beam energies, $\sqrt{\rm s_{\rm NN}}$, of 7.7, 11.5, 19.6,
27, 39, 62.4 and 200 GeV. Lattice and phenomenological...

Exploring the QCD phase diagram
Oral Presentation
We discuss the effects of the global baryon and electric charge conservation on the cumulants of net baryon and net proton fluctuations [1], which are considered to be sensitive probes of the QCD critical point. We show that the cumulants are substantially suppressed if the conservation laws are taken into account. We propose a new observable that is not influenced by the global baryon...

Exploring the QCD phase diagram
Oral Presentation
One of the main goals of the RHIC Beam Energy Scan (BES) Program is to search for the QCD Critical Point and the phase boundary in the QCD phase diagram. Higher moments of event-by-event net-proton multiplicity distributions have high sensitivity to the correlation length[1], and they are directly connected to the susceptibilities in the Lattice Gauge Theory (LGT) calculations and the Hadron...

Exploring the QCD phase diagram
Oral Presentation
Recent results from the study of nucleus-nucleus as well as
proton-proton collisions at the CERN SPS energies from
experiment NA49 and its successor NA61/SHINE will be summarized.
New results from a novel fluctuation analysis and from the search
for the critical point of strongly interacting matter will
be discussed. First measurements from NA61 of the energy dependence
of...
