486. Net baryon fluctuations from ALICE at the LHC

Anar Rustamov (National Nuclear Research Center (AZ))

Correlations and Fluctuations

Oral

Fluctuations of conserved charges are interesting probes of critical phenomena and freeze-out conditions in strongly interacting matter. In this context, experimental results will be presented on event-by-event analysis of net baryon fluctuation measurements in Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV, recorded by the ALICE Collaboration at the CERN LHC. In addition to net-protons, used as...

449. Measurement of the cumulant of net-proton multiplicity distribution in Au+Au collisions at $\sqrt{s_{NN}}$ =7.7-200 GeV from the STAR experiment

Correlations and Fluctuations

Oral

One of the main goals of the RHIC Beam Energy Scan program is to search for the QCD Critical Point (CP) and phase transition in heavy-ion collisions. Fluctuations of conserved quantities are highly sensitive to the correlation length, and are directly connected to the susceptibilities in the Lattice QCD. Therefore, they are ideal observables for finding the CP and phase transition...

697. Conserved charge fluctuations at vanishing and non-vanishing baryon chemical potential from lattice QCD

Frithjof Karsch (Brookhaven National Laboratory)

Correlations and Fluctuations

Oral

Up to $6^{th}$ order cumulants of fluctuations of net baryon-number,
net electric charge and net strangeness as well as correlations among
these conserved charge fluctuations are now being calculated in lattice
QCD. These cumulants provide a wealth of information on the properties
of strong-interaction matter in the transition region from the low
temperature hadronic phase to the...

37. Cumulants and Correlation Functions vs the QCD phase diagram

Adam Bzdak (AGH University of Science and Technology)

QCD at High Temperature

Oral

We will discuss the relation between particle number cumulants and multi-particle correlation functions. It is argued that measuring couplings of the genuine correlation functions could provide cleaner information on possible non-trivial dynamics in heavy-ion collisions. We extract integrated multi-particle correlation functions from the presently available experimental data on proton...

634. Azimuthally differential pion femtoscopy relative to the second and third harmonic in Pb-Pb 2.76 TeV collisions from ALICE

Mohammad Ahmad Saleh (Wayne State University (US))

Correlations and Fluctuations

Oral

Azimuthally differential femtoscopic measurements, being sensitive to spatio-temporal characteristics of the source as well as to the collective velocity fields at freeze-out, provide very important information on the nature and dynamics of the system evolution. While the HBT radii modulations with respect to the second harmonic event plane reflect mostly the spatial geometry of the source,...

491. Measurement of forward-backward multiplicity correlations in pp, pPb and PbPb collisions with the ATLAS detector

Mingliang Zhou (State University of New York (US))

Correlations and Fluctuations

Oral

Recently, theoretical and experimental studies of flow and multiplicity correlations in the longitudinal direction in heavy ion collision have revealed a rich dynamics not probed by traditional measurements that focused only on the transverse direction. Event-by-event longitudinal fluctuations in the initial conditions are expected to result in a strong asymmetry in particle multiplicities at...
