Abstract:
Since the discovery of charm quark in 1974, charmonium spectroscopy has always been an ideal place for exploring the non-perturbative regime of QCD. In recent years, many new particles, called XYZ particles were discovered in the charmonium energy region. They are not compatible with conventional charmonium and are recognized as good candidates for QCD exotic hadrons, which is beyond the naïve meson and baryon picture. In this talk, I will introduce these XYZ particles, and also report the recent progress in exotic hadron studies.
Brief Biography:
Prof. Zhiqing Liu got his PhD from IHEP, CAS in 2013. Then he moved to JGU Mainz as a postdoc. He won the Marie Curie Fellowship (International Incoming Fellow) during his stay in Germany. In 2018, he was selected by a national program for overseas young researchers, and employed as a professor by Shandong University. His interest focuses on hadron physics and spectroscopy, and he has wide research experience with the BESIII, Belle/Belle II, and PANDA experiments. During his PhD studies, he deeply involved in the observation of the Zc(3900) resonance by BESIII and Belle in 2013, which later was widely reported as the first confirmed particle containing four quarks. In 2020, he was awarded the C. N. Yang Prize by AAPPS & APCTP, for his “outstanding contributions to experimental hadron physics that goes beyond the quark model”.
