Abstract: The Standard Model of the strong and electroweak interactions has successfully passed many tests. Arguably its last frontier is the formation of the bound states made of quarks and gluons, the hadrons and nuclei. Traditionally, hadron and nuclear physics have been considered as two disjoint fields. I advocate a unified view and discuss the appearance of molecular structures in hadron and nuclear physics, triggered by the renewed interest in hadron spectroscopy due to the findings of many so-called exotic states. This leads to a new paradigm for the hadron spectrum, that was conventionally considered as a collection of quark model states.  

Bio: Prof. Dr. Ulf-G. Meißner is a full professor in theoretical physics and the leader of the theory group of the Helmholtz Institute for Radiation and Nuclear Physics at Bonn University. He is a renowned strong interaction physicist. Being the leader of a world-leading team on theoretical nuclear and hadron physics, he is the director of the Institute for Nuclear Physics-3 (IKP-3) and director of the Institute for Advanced Simulation-4 (IAS-4) at the Jülich Research Center. He was the dean of the Faculty of Natural Sciences and Mathematics, Bonn University, from 2008 to 2016. Here are a few among the many awards and honors he received: ERC Advanced Grant (2021), CAS President’s Fellowship for Distinguished Scientists (2018), Lise-Meitner Prize of the European Physical Society (2016), member of Academia Europaea (2010), Fellow of the American Physical Society (2009). He is also the Spokesperson of the Sino-German Collaborative Research Center CRC110. He has published more than 700 papers with a total citation of more than 74000 and an h-index of 115.
