The "International Workshop on QCD Exotics" will be held in Jinan, China, on 8-12 June, 2015. This meeting will be hosted by Shandong University and jointly organized by the Institute of High Energy Physics, Chinese Academy of Sciences and Shangdong University.
Purpose of the workshop:
There has been a lot of progress in the experimental and theoretical study of the quarkonium and quarkonium-like XYZ states. In particular, various physical pictures were confronted with the recent observations. However, so far there has not been a single state for which the mission to identify the nature is fully accomplished. The purpose of the workshop is to bring together theoreticians and experimentalists to discuss what is necessary from the theoretical side to disentangle the different scenarios proposed as well as what is feasible experimentally in this respect in the foreseeable future.
Key issues to be discussed are:
1) Identify smoking guns for the individual scenarios proposed as interpretation for the potentially exotic XYZ states. Those might include cross section line shapes, decay patterns, angular distributions etc.
2) Any possible way to recognize the "unquenched" features arising from the quark model? What do the insights of the large Nc limit imply for the physical world?
3) What can we learn from the pion mass dependence of the masses of the XYZ-states?
4) What is necessary for extracting multi-channel resonances from lattice data?
5) Which experimental measurements should be carried out in order to provide more constraints on the various theoretical approaches? Which observables can BESIII, LHCb, PANDA and Belle II deliver in the future and what insights can we gain from those?
A registration fee of RMB 1200 yuan will be charged to each participant upon registration to cover meals, one reception and one banquet, and coffee breaks during the workshop.
