NSTAR 2022

The 13th International Workshop on the Physics of Excited Nucleons - will take place at Santa Margherita Ligure, Genova, Italy  from October 17th to 21st, 2022.

The study of the nucleon excitation spectrum provides a powerful opportunity to improve our understanding of QCD in the strong-coupling regime. The NSTAR workshop aims at bringing upon expertise from both experiment and theory to focus on the physics of 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,  explore how together they can build a picture of nucleon excitations and the nature of QCD in the low-energy regime and to discuss the future developments.

The program will comprise a series of invited plenary talks, together with contributed parallel sessions.
