Abstract:

The observation of X(6900) by the LHCb Collaboration in the di-J/psi spectrum has provided a strong evidence for the fully-heavy tetraquark states. While it has triggered tremendous theoretical efforts on the understanding of their structures, it also raises questions on the phenomenological consequences. In this talk I will stress some crucial issues concerning the production mechanisms and discuss some possible criteria for QCD exotics.

About the speaker:

Qiang Zhao (Prof. Dr. of Physics) received his B.S., M.S. and Ph.D. from Peking University during 1988-1998. He worked as a postdoc in the Institut de Physique Nucleaire (IPN-Orsay), France, during 1998-2000, and later as a postdoc and EPSRC Advanced Research Fellow in University of Surrey, UK. He joined IHEP as a full professor in 2005 working in the field of theoretical hadron physics and high-energy nuclear physics. In 2014, he received the NSFC Outstanding Youth grant, and in 2019 he was awarded the prestigious Chinese Physical Society “WU You-xun (WOO Yui-hsun) Prize”.
