The bizarre hadrons accurately predicted by Professor Shilin Zhu’s group of the School of Physics in 2012 were discovered for the first time in experiments

Recently, the CERN Large Hadron Collider Bottom Quark Detector (LHCb) experimental group announced at the European Physical Society’s High Energy Physics Conference (EPS-HEP) that it has detected two charm quarks, an anti-up quark and one Reverse the four-quark state TCC+ of the down quark, thus confirming the bicharm strange hadron state composed of DD* meson predicted in 2012 by Professor Shilin Zhu and collaborators of the School of Physics

On July 29, 2021, the Large Hadron Collider beauty (LHCb) experimental group of the European Center for Nuclear Research (CERN) at the European Physical Society Conference on High Energy Physics (European Physical Society Conference on High Energy Physics) , EPS-HEP) announced the detection of a four-quark particle labeled TCC+; this is the longest-lived exotic matter particle ever discovered, and it is the first time it has been discovered.

In recent years, large-scale international experiments in high energy physics have successively discovered some strange hadrons composed of four quarks or five quarks, and most of them contain a pair of positive and negative charm quarks at the same time

In 2012, the research group of Professor Shilin Zhu from the School of Physics of Peking University and the State Key Laboratory of Nuclear Physics and Nuclear Technology cooperated with the research group of Professor Liu Xiang from the School of Physics and Technology of Lanzhou University, and firstly analyzed the isospin breaking effect of the X(3872) system.

Shilin Zhu’s research group has been engaged in the study of non-perturbative strong interactions for a long time.
