Non-central heavy-ion collisions have large ($\sim 10^{3} \hbar$) angular momentum which may be transferred, in part, to the quark-gluon plasma through shear forces that generate a vortical substructure in the hydrodynamic flow field. The vortical nature of the system is expected to polarize emitted hadrons along the direction of system angular momentum. $\Lambda$ and $\overline{\Lambda}$...
In hydrodynamic approach to heavy ion collisions, hadrons with nonzero spin produced out of the fluid can acquire polarization via spin-vorticity thermodynamic coupling mechanism [1]. The hydrodynamical quantity steering the polarization is the thermal vorticity, that is minus the antisymmetric part of the gradient of four-temperature field $\beta^\mu=u^\mu/T$.
Based on this idea, it has been...
We study the correlation between the primordial electromagnetic (EM) fields
$\vec{E}$ and $\vec{B}$ and the initial matter geometry in p+Pb collisions.
The angular correlation between $\vec{B}$ and the second eccentricity harmonic
$\vec{\varepsilon}_2$ is substantially diminished in p+Pb compared to heavy ion
collisions (HICs), while those between $\vec{E}$ and the first eccentricity
harmonic...
In non-central heavy-ion collisions unprecedented strong magnetic fields are expected to be produced (O 1018 Gauss), whose interplay with quantum anomalies of the Quark-Gluon Plasma (QGP) has been predicted to lead to a number of interesting phenomena, such as the Chiral Magnetic Effect (CME). While several experimental observations are partially consistent with predictions of a CME signal, it...
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 the fluid dynamics framework. Experimental observation of CME is of great interest and has been reported in Dirac and Weyl semimetals. Significant efforts have also been made to search for CME in heavy ion...
In this talk, I will review the current status of theoretical studies of magnetic filed and associated observables in heavy-ion collisions. I will focus on the Chiral Magnetic Effect and discuss new ideas aiming at its unique identification. Specifically I will present the case for colliding nuclear isobars and report on
theoretical predictions and expectations.
