“…This is important because, by construction, the correlator v n q 3 − q 3 v n contains reducible correlations, i.e., correlations that can be expressed in terms of lower order correlations [33,34]. These reducible correlations are removed by the construction v n q 3 − q 3 1 v n , which is therefore a three-point cumulant.…”

We report on measurements of a charge-dependent flow using a novel three-particle correlator with ALICE in Pb-Pb collisions at the CERN Large Hadron Collider (LHC), and discuss the implications for observation of local parity violation and the chiral magnetic wave (CMW) in heavy-ion collisions. Charge-dependent flow is reported for different collision centralities as a function of the event charge asymmetry. While our results are in qualitative agreement with expectations based on the CMW, the nonzero signal observed in higher harmonics correlations indicates a possible significant background contribution. We also present results on a differential correlator, where the flow of positive and negative charges is reported as a function of the mean charge of the particles and their pseudorapidity separation. We argue that this differential correlator is better suited to distinguish the differences in positive and negative charges expected due to the CMW and the background effects, such as local charge conservation coupled with strong radial and anisotropic flow.

Anomalous transport coefficients are known to be universal in the absence of dynamical gauge fields. We calculate the corrections to these universal values due to dynamical gluon fields at strong coupling, at finite temperature and finite density, using the holographic duality. We show that the consistent chiral magnetic and chiral vortical currents receive no corrections, while we derive a semi-analytic formula for the chiral separation conductivity. We determine these corrections in the large color, large flavor limit, in terms of a series expansion in the anomalous dimension ∆ of the axial current in terms of physical parameters ∆, temperature, electric and chiral chemical potentials and the flavor to color ratio N f Nc . Our results are applicable to a generic class of chiral gauge theories that allow for a holographic description in the gravity approximation. We also determine the dynamical gluon corrections to the chiral vortical separation current in a particular example in the absence of external axial fields. arXiv:1806.07138v2 [hep-th] 26 Feb 2019 R α βµν is the Riemann tensor of the background geometry. The anomaly coefficients a 1 , a 2 and a 4 are examples of the first type whereas a 3 is of the second type. All are known to be one loop exact [18].The purpose of our paper is to explore the contribution of the second, dynamical, type of anomalies to anomalous transport in strongly coupled chiral gauge theories. We study the problem using the AdS/CFT correspondence [19][20][21]. In particular we calculate, using AdS/CFT, the transport coefficients that characterize the anomalous transport properties of the system, including the contribution from the dynamical type anomalies.1 See the review [5] for a recent account.

“…A fully quantitative theoretical approach to the description of charge asymmetries requires the use of relativistic hydrodynamics that includes the terms arising from the chiral anomaly, Charged-hadron correlator as a function of collision centrality (deduced from the observed particle multiplicity) measured by the ALICE Collaboration (81). supplemented by the initial conditions describing topological fluctuations at the early stage of a heavy-ion collision.…”

Gauge theories with compact symmetry groups possess topologically nontrivial configurations of gauge field. This characteristic has dramatic implications for the vacuum structure of quantum chromodynamics (QCD) and for the behavior of QCD plasma, as well as for condensed matter systems with chiral quasi-particles. I review the current status of this problem with an emphasis both on the interplay between chirality and a background magnetic field and on the observable manifestations of topology in heavy-ion collisions, Dirac semimetals, neutron stars, and the early Universe. 193
