Abstract:
With recent experimental evidence for tetr aquarks and pentaquarks\, hadron spectroscopy is nowadays a cutting-edge a rea of research with the LHC among its central facilities. Hadrons are bou nd states of quarks and gluons in QCD\, the theory of the strong interacti on\, but their spectrum and structure are much richer than the naïve quar k model suggests and governed by nonperturbative phenomena such as confine ment and dynamical mass generation.

In this colloquium I will mak e a survey through some open questions in QCD\, with an emphasis on the st ructure of exotic hadrons and multiquarks\, and connect them with the key underlying phenomena of mass generation for quarks and gluons. I will high light recent advances with functional methods\, which allow one to compute hadron properties from first principles. Systematic improvements in this approach have made it possible to address a wide range of problems from mu ltiquark spectroscopy to form factors\, parton distributions\, the anomalo us magnetic moment of the muon\, and the QCD phase diagram.

Sh ort Bio:
My research is centered around nonperturbative phenomena in QCD and nuclear and hadron physics\, including hadron and multiquark sp ectroscopy and structure\, Compton scattering and the muon g-2 problem. I obtained my PhD degree at the University of Graz (Austria) and carried out research stays at Argonne National Laboratory (USA)\, TU Darmstadt\, and the University of Giessen (Germany). In 2017 I moved to IST Lisboa within an FCT Investigator Grant\, and in 2020 our group NPStrong joined LIP.
