We make phenomenological predictions for particle spectra and flow in heavy-ion collisions using 3+1d anisotropic hydrodynamics (aHydro) including the effects of both bulk and shear viscosities. The dynamical equations necessary are derived by taking moments of Boltzmann equation allowing for three distinct momentum-space anisotropy parameters. The formulation is based on relaxation-time...
The azimuthal anisotropy coefficient $v_2$ is a good tool to investigate
properties of the QGP not only to study collective flow, but also the energy loss of hard scattered partons. For non-central collisions,
the collision area has an elliptic shape. When the hard scattered partons
created in the collision are emitted, they have different path-lengths
interacting with QGP depending on the...
Experiments at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) probe the properties of nuclear matter at extremely high temperatures and densities. Hadronic observables in the final stage of the heavy ion collision can be described well by fluid dynamics or blast wave parameterizations. We improve existing blast wave models by adding shear viscous corrections to...
Using an anomalous transport model for massless quarks, we study the effect of magnetic field on the elliptic flows of quarks and antiquarks in relativistic heavy ion collisions. With initial conditions from a blast wave model and assuming that the strong magnetic field produced in non-central heavy ion collisions can last for a sufficiently long time, we obtain a substantial electric...
The forces that drive the nuclear collision system towards local thermal equilibrium leave few observable traces. Heavy ion experiments report a range of features widely attributed to the hydrodynamic flow of a near-equilibrium quark gluon plasma. In particular, measurements of azimuthal anisotropy provide the most comprehensive support for the hydrodynamic description of these systems. In...
In relativistic heavy-ion collisions, J/𝜓 mesons can be produced via different mechanisms, and the large mass of the charm quark makes these mesons a valuable probe to the thermalization of the medium. The study of J/𝜓 azimuthal anisotropy allows for a disentanglement of various production processes and access to charm quark azimuthal anisotropy. J/𝜓 produced from direct pQCD processes have...
