Quarkonium with Effective Field Theories

Department of Physics and Astronomy Colloquium: Prof. Nora Brambilla, Technical University of Munich, to speak on "Quarkonium with Effective Field Theories."

Abstract:
Quantum Chromodynamics (QCD) is the sector of the Standard Model of particle physics that describes the strong interaction. It is deceptively simple to formulate but notoriously difficult to solve. Heavy quarkonium is a multiscale system that probes the different energy regimes of QCD, from the high-energy region, where an expansion in the coupling constant is possible and precision studies may be done, to the low-energy region, dominated by confinement and the many manifestations of the nonperturbative strong dynamics. Properties of production and absorption of quarkonium in a medium are also crucial for the study of QCD at high density and temperature.

On the theoretical side, the construction of new nonrelativistic effective field theories for quarkonium has recently revolutionized the field, providing both a conceptual framework and a powerful calculational tool. On the experimental side, the diversity, quantity and accuracy of the data collected in the last few years at Belle, BESIII and at LHC experiments is impressive, featuring the observation of new states and new unexpected processes. I will discuss these theoretical and experimental advancements and their implications for our understanding of strong interactions.
