Title: Probing QCD Dynamics in Heavy Quark-Antiquark Systems

Speaker: Prof. Estia Eichten (Fermi Lab, USA)

Time: 10:00AM, May 3rd (Fri.)

Place: Theory Division，319

Abstract:

The speaker will review what has been learned about the dynamics of QCD from theoretical and experimental studies of heavy quark-antiquark systems ($c\bar c$ and $b\bar b$). Theoretical expectations in the non-relativistic limit (augmented by lattice QCD studies) are compared to existing experimental results for spectrum and decays. The role of the recently observed (XYZ) states as well as other present puzzles and future opportunities are discussed.
