Collective Dynamics

Oral

Strong fluctuations of the elliptic flow in heavy ion collisions allow an efficient selection of the events corresponding to a specific initial geometry. This technique, Event Shape Engineering, was applied to select events corresponding to the
same centrality, but having very different values of elliptic flow. For those events, we present results on the centrality dependence of the...

Collective Dynamics

Oral

The quark-gluon matter produced in relativistic heavy-ion collisions may contain local domains in which P and CP symmetries are not preserved. When coupled with an external magnetic field, such P- and CP-odd domains will generate electric currents along the magnetic field --- a phenomenon called the chiral magnetic effect (CME). Recently, the STAR Collaboration at RHIC and the ALICE...

446. Disentangling flow and signals of Chiral Magnetic Effect in U+U and Au+Au collisions

Collective Dynamics

Oral

We present measurements of the charge-dependent, three-particle correlator \gamma=<cos(\phi1+\phi2-2\phi3)> and elliptic flow v2 in central and ultra-central U+U and Au+Au collisions at sqrt{sNN}=200 GeV from STAR. The difference \Delta \gamma = \gamma(like- sign)-\gamma(un-like sign) measures charge separation across the reaction plane, a predicted signal of the Chiral Magnetic Effect (CME)...

377. Observation of charge-dependent azimuthal correlations in pPb collisions with CMS and its implication for the search of the Chiral Magnetic Effect

Correlations and Fluctuations

Oral

Charge-dependent azimuthal correlations relative to the event plane in AA collisions have been suggested as providing evidence for the chiral magnetic effect (CME) caused by local strong parity violation. However, the observation of the CME remains inconclusive because of several possible sources of background correlations that may account for part or all of the observed signals. This talk...

167. Quantifying Chiral Magnetic Effect from Anomalous Viscous Fluid Dynamics

Collective Dynamics

Oral

Abstract:

Chiral Magnetic Effect (CME) is the macroscopic manifestation of the fundamental chiral anomaly in a many-body system of chiral fermions, and emerges as anomalous transport current in hydrodynamic framework. Experimental observation of CME is of great interest and significant efforts have been made to look for signals of CME in heavy ion collisions. Encouraging evidence of...

240. Chiral magnetic effect and anomalous transport from real-time lattice simulations

New Theoretical Developments

Oral

We present a first principles approach to study the dynamics of the Chiral Magnetic Effect and Chiral Magnetic Wave based on real-time lattice simulations with dynamical (Wilson and Overlap) fermions simultaneously coupled to color and electro-magnetic fields. We discuss how these techniques can be used to study the Chiral Magnetic Effect during the pre-equilibrium stage of a heavy-ion...
