12. Charmonium production within the Statistical Hadronisation Model

Markus Koehler (University of Heidelberg)

Quarkonia

We will report on recent developments of charmonium production within the statistical hadronisation model. Charmonium production as a function of centrality, rapidity and transverse momentum will be presented and compared to available LHC data. The model can be extended to all charmed mesons and baryons. Predictions for the transverse momentum spectra of exotic charmonium states are made for...

5. Recent Results on Lattice QCD at non-zero temperature and density

Peter Petreczky (BNL)

Quarkonia

I will discuss recent lattice QCD results on equation of state, transition temperature, fluctuations of conserved charges and color screening at vanishing and non-zero baryon density. I will show new results on the equation of state in 2+1 flavor QCD up to temperature 2000 MeV and recent results from Taylor expansion in baryon chemical potential for equation of state and the transition...

10. ϒ-meson dissociation in Pb+Pb collisions at LHC energies and the role of the electromagnetic field

Johannes Hölck (Institut für Theoretische Physik der Universität Heidelberg)

Quarkonia

We investigate the suppression of ϒ mesons in the hot quark–gluon plasma (QGP) created in Pb+Pb collisions at energies available at the CERN Large Hadron Collider using a centrality- and transverse-momentum-dependent model that encompasses screening, collisional damping, and gluodissociation in the QGP. For ϒ(1S), the model prediction is compatible with experimental data from the CMS...

4. On nonequilibrium quarkonium evolution in the QGP fireball

Yan Zhu (TUM)

Quarkonia

A Lindblad equation for the evolution of heavy quarkonia in QGP has recently been derived from potential non-relativistic QCD (pNRQCD) and open quantum system framework. We derive the classical limit of the evolution equations for color-singlet and color-octet quarkonia states. Within the classical approximations, we are able to write the evolution equations respectively as a Langevin equation...

13. sPHENIX at RHIC: Science mission and status

Gunther Roland (MIT)

07/09/2018, 12:05

Quarkonia

The science mission of the sPHENIX experiment, outlined in the 2015 US Nuclear Physics long range plan, calls for studies of the microscopic structure of the QGP through state-of-the-art jet, upsilon and heavy flavor measurements at RHIC, complementing similar measurements at LHC. We will discuss highlights of the proposed sPHENIX science program and describe the design and construction status...
