Speaker: Bing-Song Zou

Location: The conference room 437 of Xingjian Building
Abstract: 
I will give some comments about “exotic” structures observed in various hadron-hadron S-wave interactions, such as why the broad s and k appear narrower in production processes than in corresponding S-wave pp and pK elastic scattering, why f0(980) has such a narrow peak; the compatibility of the S-wave KL near-threshold enhancement from BES and COSY experiments, and its implication on properties of N*(1535); the BES pp S-wave near threshold enhancement and final-state-interaction by t-channel meson exchanges; the L(1405) and N*(1535) as S-wave KN and KS bound states, respectively, and their charm and beauty partners; Explaining the many threshold structures in the heavy-quark hadron spectrum and so on.
About the speaker:
Bing-Song Zou received his Ph.D degree of Physics from the Institute of Theoretical Physics, Chinese Academy of Sciences in 1990. After working in Europe for 8 years, he became a full professor at the Institute of High Energy Physics, CAS, in 1998, and moved to ITP, CAS in 2012. His main research interests are the strong interactions in nuclear and particle physics.
