Hadron physics
(led by Petr Bydžovský)
The scientific activity of the group is dedicated to physics of hadrons and baryonic systems at low energies, a field at the intersection of particle and nuclear physics, as well as astrophysics. It is of fundamental importance for our understanding of the visible matter in the Universe - the strong interactions, structure of bound and resonant states, and properties of hadrons in the nuclear medium. In particular, we focus on baryon-baryon and meson-baryon interactions, few- and many-body exotic systems with nonzero strangeness, as well as production of hadrons and hypernuclei. We employ state-of-the-art approaches, such as large-scale ab initio calculations, dynamically exact three- and four-body Faddeev equations, and effective field theory. Our work is closely related to experiments at world-leading international laboratories and we intend to expand our research activities in accordance with their scientific programs, e.g. to the charm and beauty sectors.
The group is well recognized in the world community working in the given area which is reflected by numerous publications, invited talks at conferences, and (co-)organization of important international meetings; e.g., HYP 2022 held in Prague, several ECT* workshops, and EMMI workshop in Trieste. In addition, members of the group established and regularly organized Indian-Summer School of Physics, a series of physics courses held since 1988.
Group of Hadrons and Baryonic Systems maintains active international collaboration with colleagues from TRIUMF (Vancouver, Canada), Chalmers University of Technology (Göteborg, Sweden), University of Washington (USA), Universitat Autònoma de Barcelona (Spain), The Hebrew University of Jerusalem (Israel), Technical University Munich (Germany), Kyoto University (Japan), Kobayashi-Maskawa Institute of Nagoya University (Japan), Bonn University (Germany), and Thomas Jefferson National Accelerator Facility (USA). In the latter we are active members of the KLF and Hypernuclear Collaborations providing theoretical support of current and planned experiments.
