NBI Heavy-ion Seminar: Correlating isotropic flow with anisotropic flow in heavy-ion collisions: nuclear phenomenology at high energy beyond the quark-gluon plasma

Thursday 6 May 2021, 11:00 → 12:30 Europe/Copenhagen

Speaker: Giuliano Giacalone (Heidelberg University)

Abstract:

Experiments conducted at the Relativistic Heavy Ion Collider and at the Large Hadron Collider have demonstrated that nuclear collisions at high energy create small droplets of quark-gluon plasma (QGP), effectively described by relativistic (viscous) hydrodynamical laws. The established fluid paradigm allows us today to exploit nuclear collisions in the search for phenomena beyond the original goals of the heavy-ion program. This can be achieved by studying multi-particle correlation observables where the measures of the anisotropy of the emission of hadrons, the so-called flow coefficients, v_n, are correlated with the magnitude of the isotropic emission, i.e., the average hadron transverse momentum, <pT>. These v_n-<pT> correlations provide in particular: i) a handle to manipulate the strong electromagnetic fields produced in the interaction of nuclei at high energy; ii) a novel means to probe the deformed global shape of the colliding ions; iii) a way to trigger manifestations of the dynamics of gluon fields in the pre-QGP stages of the collision process. I point out additional phenomena that can be analyzed with the same techniques, and emphasize that experimentally it will be possible to pursue such studies with success over the next decade.
