35. Quarkonium production at LHC from pp to AA

Dr Enrico Scomparin (INFN Torino, Italy)

2/1/17, 4:00 PM

The study of the production of quarkonia in heavy-ion collisions represents one of the most important tools for the characterization of the Quark-Gluon Plasma. In particular, the screening of the color force in a deconfined medium is predicted to lead to a suppression of the production of charmonium and bottomonium states with respect to the yields observed in pp collisions. At the same time,...

222. Heavy quarkonium at finite temperature from lattice effective field theories

Dr Alexander Rothkopf (Institute for Theoretical Physics, Heidelberg University)

2/1/17, 4:25 PM

Heavy quarkonium presents a unique probe of the quark-gluon plasma produced in relativistic heavy-ion collisions. While Bottomonium is expected to act as a test particle traversing the medium in the collision center, recent measurements of finite J/ψ flow by the ALICE collaboration hint at the participation of the charm quarks in the collectivity of the bulk. Here we present our recent...

17. Color screening in high temperature quark-gluon-plasma

Dr Johannes Heinrich Weber (Technische Universität München)

2/1/17, 4:50 PM

I discuss lattice calculations of the Polyakov loop and of Polyakov loop correlators for QCD with 2+1 flavors and almost physical quark masses using the highly improved staggered quark action (HISQ). I elucidate how the Polyakov loop and related observables behave in the crossover region and how these observables probe the deconfinement aspects of the crossover. I examine the short- and...
