7. Quarkonium production in the Statistical Hadronization Model

Anton Andronic (Muenster University)

Week 4

Assuming full screening of quarkonia in QGP as well as full thermalization of charm quarks in QGP, quarkonium production in the Statistical Hadronization Model occurs at chemical freeze-out (which, for high energies, likely coincides with the QCD phase boundary). The model describes very well the LHC J/psi data on centrality, transverse momentum and rapidity dependence and gives definite...

9. From Heavy-Flavor Transport to Microscopic Properties of the Quark-Gluon Plasma

Week 4

Heavy-flavor particles are believed to be versatile probes of the medium produced in high-energy nuclear collisions. Their masses provide a large scale which implies several benefits in the theoretical and phenomenological analysis of their vacuum and in-medium properties. We discuss a selfconsistent many-body approach that allows for a comprehensive description of both bound and scattering...

13. In-medium properties of heavy flavor mesons from lattice QCD

Peter Petreczky (BNL)

18/09/2018, 09:30

Week 4

I will review recent progress in studying the in-medium properties of open heavy flavor mesons and quarkonia from lattice QCD. I will report on recent results on in-medium spectral functions for bottomonia and charmonia from non-relativistic
QCD (NRQCD). Discuss new results on the determination of the complex heavy quark potential on the lattice. Furthermore, I will show results on spatial...

26. In-medium effects in the spectrum of baryons

Chris Allton (Swansea University)

Week 4

Baryons with various strange content are studied across the deconfinement transition using our Nf=2+1 flavour anisotropic FASTSUM lattices. Below Tc we find that the positive-parity states are largely temperature independent, whereas the negative-parity hadron masses decrease as Tc is approached. Near, and above Tc, the parity partners' masses converge, with parity doubling being closest for...

17. The static hard-loop gluon propagator to all orders in anisotropy

Michael Strickland (Kent State University)

20/09/2018, 09:30

Week 4

We calculate the (semi-)static hard-loop self-energy and propagator using the Keldysh formalism in a momentum-space anisotropic quark-gluon plasma. The static retarded, advanced, and Feynman (symmetric) self-energies and propagators are calculated to all orders in the momentum-space anisotropy parameter ξ. For the retarded and advanced self-energies/propagators, we present a concise derivation...

11. Open quantum systems approach to the study of quarkonium suppression

Miguel Ángel Escobedo Espinosa (University of Jyväskylä)

21/09/2018, 09:30

Week 4

Heavy quarkonium related observables are very useful to obtain information about the medium created in relativistic heavy ion collisions. In recent years the theoretical description of quarkonium in a medium has moved towards a more dynamical picture in which decay and recombination processes are very important. In this talk we will discuss the equations that describe the evolution of the...
