Research Interests

Liu Beijiang’s prolonged efforts at BESIII experiment made ground-breaking contributions to the physics of exotic hadrons. He is the principal contributor to the recent observation of the isoscalar, η1(1855), with exotic quantum numbers 1-+, which opens a new direction for the study of spin exotics. This is an observation of a new category of hadronic matter, which is an important step forward in hadron spectroscopy and attracts attention from the international community. He is leading the research of glueballs at BESIII, which provided critical information to the long-standing issue of hadron physics. He pioneered the GPU acceleration in PWA, which is a keystone for the hadron spectroscopy at BESIII. His efforts also include the foundational contribution to the alignment of BESIII’s tracking system and applications of machine learning in hadron physics. He has been invited to give plenary talks at HADRON, ICHEP, PIC and many other international conferences.
