报告摘要：In July 2021 the LHCb Collaboration announced the discovery of a new type of exotic hadron -- a doubly-charmed tetraquark $T_{cc}^+$, whose mass agrees precisely with a 2017 theoretical prediction. I will discuss the recent related experimental and theoretical developments regarding new types of hadrons involving heavy quarks: tetraquark and pentaquark hadronic molecules, doubly heavy baryons, stable tetraquarks and others.
个人简介：Prof. Marek Karliner is Professor of Physics at Tel Aviv University in Israel, working in the field of theoretical physics of elementary particles. His recent research includes several theoretical predictions for properties of unusual combinations of quarks, known as tetraquarks and pentaquarks, subsequently confirmed by experimental work at CERN, US, China and Japan. Prof. Karliner is incumbent on the Edouard and Francoise Jaupart Chair of Theoretical Physics of Particles and Fields. Since 2015, he has been the Director of the Mortimer and Raymond Sackler Institute of Advanced Studies at Tel Aviv University. Since 2017, he has been a Foreign Member of the Polish Academy of Arts and Sciences. Since 2021 he has been the Chairman or the Israel Committee for High Energy Physics and the Scientific Representative of Israel in the CERN Council. From 2021 he has also been a member of the Supervisory Council of Warsaw University in Poland. In April 2023 he has been elected as Fellow of the Israel Physical Society.
