Title: Recent pentaquark study at LHCb

Speaker: Prof. Liming Zhang

Abstract:

In2015 the LHCb collaboration reported observation of significant J/psi ppentaquark structures in the $\Lambda_b^0 -> J/\psi p K^-$ decayusing Run 1 data. This is a major turning point in the exotic baryonspectroscopy. At this seminar, an update on this pentaquark study withfull Run 1 and 2 data collected by the LHCb detector will be presented. Newpentaquark state and more complex structures are observed. Other recent pentaquarkstudy will be also discussed.

About speaker:

He received his Ph.D. from the Department of Modern Physics of the University ofScience and Technology of China (USTC) in 2006. He is an associate professor inthe Department of Engineering Physics of Tsinghua University, working at theLHCb experiment. His research interests are measurements of B meson mixing andCP violation, and studies of conventional and exotic hadron spectroscopy. Hehas contributed to more than 30 academic papers.
