	4	Strategies for baryon resonance analysis显示文摘The analytic properties of scattering amplitudes provide a meeting point for experimental and theoretical investigations of baryon resonances. Pole positions and residues allow for a parameterization of resonances in a well-defined way which relates different reactions. The recent progress made within the Jlich model is summarized.	M.

	5	Resonance properties from a coupled channel meson exchange model显示文摘In this talk, I present the results on the pole structure of pion-nucleon scattering in an analytic model based on meson exchange. The analytic properties of scattering amplitudes provide important information. Besides the cuts, the poles and zeros on the different Riemann sheets determine the global behavior of the amplitude on the physical axis. Pole positions and residues allow for a parameterization of resonances in a well-defined way, free of assumptions for the background and energy dependence of the resonance part. This is a necessary condition to relate resonance contributions in different reactions.	M. Dring C. Hanhart 黄飞 S. Krewald U.-G. Meiβner	2009	Chinese Physics C2009，33，12：	0
	6	Forward pion-nucleon charge exchange reaction and Regge constraints显示文摘We present our recent study of pion-nucleon charge exchange amplitudes above 2 GeV. We analyze the forward pion-nucleon charge exchange reaction data in a Regge model and compare the resulting amplitudes with those from the Karlsruhe-Helsinki and George-Washington-University partial-wave analyses. We explore possible high-energy constraints for theoretical baryon resonance analyses in the energy region above 2 GeV. Our results show that for the pion-nucleon charge exchange reaction, the appropriate energy region for matching meson-nucleon dynamics to diffractive scattering should be around 3 GeV for the helicity flip amplitude.	黄飞 A. Sibirtsev S. Krewald C. Hanhart J. Haidenbauer U.-G. Meiβner	2009	Chinese Physics C2009，33，12：	0
