The primary subject in the research of high-energy heavy-ion collisions is to understand the nuclear matter produced in these interactions.
Bottomonia have been considered as golden probes to study the properties of such matter, as they are produced at early stages of collisions via hard-scattering processes. Also, their spectral functions are modified by Debye screening and interactions with...
In recent years, a lot of work has been done towards a dynamical description of quarkonia inside the QGP, using the open quantum systems formalism. In this framework, one can get a real-time description of a quantum system (here the quarkonium) in interaction with a thermal bath (the QGP) by studying the system reduced density matrix.
The first part of the talk will be devoted to a review...
Quarkonium suppression is one of the probes of the formation of a quark-gluon plasma in heavy-ion collisions. Three phenomena influence the evolution of quarkonium in a medium: screening, collisions with medium partons and recombination. A formalism in which all these mechanisms can be described consistently is that of open quantum system. In this talk, I will review how to combine the open...
The quark-gluon plasma (QGP) is a strongly-interacting deconfined state of matter produced in ultra-relativistic heavy-ion collisions. In order to study the QCD matter phase of its evolution, quarkonia, bound states of a heavy quark and antiquark pair, are preferred tools as they are sensitive to the first stages of the collision and to the evolution of the created system.
Measurements of...
Quarkonium suppression in heavy ion collisions has been used as a probe of the quark-gluon plasma (QGP) for decades. The intuitive picture of sequential suppression based on the Debye screening of the heavy quark potential is obscured by other in-medium processes such as dissociation and recombination. A natural question to ask is what we can learn about the QGP from measurements of quarkonium...
We will review the status of the NLOAccess Virtual Access.
