Press Release
The international research group including Yan Lyu (former Student Trainee from Peking Univ., iTHEMS), Takumi Doi (Senior Research Scientist, iTHEMS) and Tetsuo Hatsuda (Program Director, iTHEMS) has theoretically unraveled the properties of the genuine tetraquark state Tcc, composed of four quarks. This research achievement is expected to contribute to the understanding of a fundamental question in modern physics: how quarks, the elementary particles, can combine to form new states of matter.
