Workshop on the Physics of Excited Nucleon – NSTAR2009 is to be hosted by the Institute of High Energy Physics (IHEP) of Chinese Academy of Sciences ( CAS ) in Beijing on April 19 – 22, 2009 The NSTAR workshop aims at bringing upon expertise from both experiment and theory to focus on the physics of excited nucleon. In addition to keeping the community being updated with the most recent experimental progresses in this field, we shall continue the conversations on 1) criteria for baryon resonance signals and how to extract their parameters from newly accumulated data; 2) progresses on Lattice simulation and phenomenological analyses; and 3) candidates of exotic states and their properties, etc.
