Heavy-Flavor Theory at “Hard and ElectromagneticProbes 2018"

Abstract

An overview is given of the theoretical developments on heavy quarks and quarkonia in heavyion collisions as reported at the "Hard and EM Probes 2018" conference. Specifically, we address progress in the understanding of heavy-flavor diffusion and its hadronization, quarkonium transport and the extraction of quarkonium melting temperatures, energy loss of heavy quarks at high momentum, and their rescattering in small colliding systems.

“…This novel state of deconfined matter [6,7] is called the (strongly interacting) quark-gluon plasma (QGP). A large variety of approaches [8][9][10][11][12][13][14][15][16][17][18][19][20] have been developed to study the properties of this QCD-medium, allowing to test in detail our understanding of the laws of nature at the subatomic scale. Unfortunately, the tiny dimensions of the QGP system under investigation and its extremely fast evolution make it inaccessible to direct measurements.…”
