NSTAR2009 1st Announcement - a message from Qiang Zhao

April 21, 2008

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.

NSTAR is a series held previously in Florida State University (1994), Jefferson Lab (1995), INT in Seattle (1996), George Washington University (1997), ECT* in Trento (1998), Jefferson Lab (2000), Mainz (2001), Pittsburg (2002), LPSC in Grenoble (2004), Florida State University (2005), and University of Bonn (2007).

Scientific Aim:

The study of nucleons and their resonances has provided a rich source of information on strong interaction physics in the non-perturbative QCD regime, and also raised fundamental questions with profound significance for our understanding of Nature.

During the past decades, there have been extraordinary developments on experimental facilities for the study of baryon properties, such as JLab, ELSA, ESRF, MAMI, and SPring-8. These facilities, via photo-nuclear reactions, provide a clean way of probing the internal structure and form factors of nucleons and their excited states, exploring connections between the nuclear medium and nucleon internal degrees of freedom, and manifesting interferences between non-perturbative and perturbative QCD dynamics. In contrast to these, an alternative method of studying the property of nucleon resonances is via charmonium decays such as J/y, which can be produced in electron-positron annihilations. With the success of energy and detector upgrade of Beijing Electron-Positron Collider (BEPC), the BES facility will become the largest t-charm factory in the world, and billions of J/y and y¢ events will be accumulated. This will make it an important complementary facility to synchrotrons and continuum electron beam facilities such as JLab in the study of baryon resonances.

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.
