NSTAR2019
The 12th International Workshop on the Physics of Excited Nucleons - will take place at Bonn University from June 10th to 14th, 2019.
The excitation spectrum of the nucleon provides a powerful tool to improve our understanding of QCD in the strong-coupling regime. Thus there are major experimental, theoretical and computational efforts that aim to explore both the spectrum and the structure of excited nucleons. Dedicated experimental programs exist to perform accurate measurements of meson photo- and electro-production off the nucleon in order to discover its excitations, and determine its internal structure. Effective field theories, QCD-inspired models and Schwinger-Dyson approaches to QCD aim to identify the key degrees of freedom describing the nucleon, while lattice QCD provides first principle calculations of a precision that can confront experiment. The purpose of this workshop is to present the latest results in each of these areas, and explore how together they can build a picture of nucleon excitations and the nature of QCD in the low-energy regime.
The program will comprise a series of invited plenary talks, together with contributed parallel sessions.
