  • Abstract:

    Our understanding of heavy baryons has expanded considerably in recent years with the discovery of many new states including charm and bottom quarks at the LHC. It is crucial to develop a theoretical understanding of such states from first principles in Quantum Chromodynamics (QCD). The goal of this project is to compute the spectrum of heavy baryons using functional methods in QCD. These methods have been successfully employed in the light-baryon sector, and our aim is to extend them to charm and bottom baryons, as well as to computations of their excitations and electromagnetic form factors. An important open question concerns relativistic effects which are crucial for light baryons, but recent studies suggest that relativity could also play an important role for charm and even bottom baryons. We will also implement current progress in the calculation of QCD's n-point functions, a key improvement towards ab-initio calculations of heavy baryons.
