H03.00001: Heavy flavor production and interactions in hot and cold QCD Invited Speaker: Ramona L Vogt Heavy flavor probes are well established probes of the hot system produced in heavy-ion collisions. Open heavy flavor production is better under control in p+p collisions than quarkonium production due to remaining uncertainties in the production mechanism. In heavy-ion collisions, quarkonium suppression and its subsequent regeneration has been described employing a number of approaches including transport models, open quantum systems and statistical hadronization. Many of these approaches employ inputs from lattice QCD on the real and impaginary parts of the quarkonium potential, spectral functions, meson correlators, and dissociation temperatures. Despite different physics inputs, most approaches claim to describe the quarkonium data. Several collaborative efforts have recently been undertaken to clarify the situation with some emphasis on bottomonium production, particularly for the sPHENIX experiment, the last new detector to be deployed at RHIC. These efforts will be discussed and initial comparative results shown. A new DOE topical collaboration to address the subject will also be introduced. |

H03.00002: Heavy flavor production and interaction in heavy Ion Collision Invited Speaker: Deepa Thomas Heavy quarks (charm and beauty) are powerful probes to study high-energy hadronic collisions. They are mainly produced in hard parton scattering processes with large momentum transfer, thus their production cross-sections can be calculated within the framework of perturbative quantum chromodynamics (pQCD). In ultra-relativistic heavy-ion collisions a hot and dense QCD matter, called Quark-Gluon Plasma (QGP), is produced. Heavy quarks have been extensively used to test pQCD in proton-proton collisions, to study different cold nuclear-matter effects in proton-nucleus collisions, and to investigate the production and properties of the QGP in heavy-ion collisions. The experimental tools used in the field of heavy-ion physics can be extended to study the structure and dynamics of hadronic matter at the future Electron-Ion-Collider (EIC). In this talk, I will present a review of heavy-flavour hadron measurements at RHIC and at the LHC, and discuss what we have learnt from these results. These measurements can form a useful input to develop a rich physics program at the EIC. |

H03.00003: Heavy quarknoium production at the EIC Invited Speaker: Vincent Cheung One of the best ways to understand hadronization in QCD is to study the production of quarkonium. The Electron-Ion Collider (EIC) will serve as a laboratory to enrich our understanding on quarkonium production beyond hadron-hadron collisions. The color evaporation model (CEM) and Non-relativistic QCD (NRQCD) are the most common models employed to describe production yields and spin-related measurements like the polarization. In this talk, we will present the recent model developments of quarkonium production models in preparation of the EIC era. |
