Understanding the structure of the hadron is of fundamental importance in
Production of heavy quarkonia is arguably one of the most fascinating subjects in strong interaction physics. It offers unique perspectives into the formation of QCD bound states. Heavy quarkonia are among the most studied particles both theoretically and experimentally. They have been and are continuing to be the focus of measurements in all high energy colliders around the world. Because of their distinct multiple mass scales, heavy quarkonia were suggested as a probe of the hot quark-gluon matter produced in heavy-ion collisions, and their production has been one of the main subjects of the experimental heavy-ion programs at the SPS and RHIC.
However, discovery of J/psi at Brookhaven National Laboratory (BNL) and SLAC National Accelerator Laboratory (SLAC) over 36-year ago, theorists still have not been able to fully understand the production mechanism of heavy quarkonia, although major progresses have been made in recent years.
With the start of LHC operation and the RHIC luminosity and detector upgrades it is expected that high-quality data samples will become available in the near future. To analyse and correctly interpret these measurements, and in order to quantify properties of the hot matter produced in heavy-ion collisions, it is necessary to improve our theoretical understanding of quarkonium production.
We believe it is very timely and important to organize an extended summer program to summarize the status of heavy quarkonium production, to focus the effort, and to lay out the future perspectives. This summer program at Brookhaven National Laboratory will be focused on theory and its interface with experimental measurements. We plan to address a wide range of theoretical aspects on the production mechanism in the vacuum as well as in cold nuclear and hot quark-gluon medium, from the controlled calculations in QCD and its effective theories such as NRQCD to various models, and to the first principle lattice calculation.
We plan to divide our program into three major scientific parts: basic production mechanism for heavy quarkonium in vacuum or in high energy elementary collisions, the formation of quarkonium in nuclear medium as well as the strong interacting quark-gluon matter produced in heavy ion collisions, and heavy quarkonium properties from the first principle lattice calculations. A particular emphasis of our program will be on the role of heavy quarkonium production at a future Electron-Ion Collider (EIC). We plan to have a relaxed and informal setting with two or three presentations by participants each day and ample time for active discussions and collaborations among the participants. In addition, we plan to have a two-and-one-half day of a focused workshop on the quarkonium production in the middle of the two-week summer program which will help provide an intense period of discussions, open exchange of ideas, a careful review of existing data and current status, and a chance to refocus the effort of the summer program.
Registered attendees are invited to attend the optional banquet dinner after the Workshop. Date and location to be determined.
