本项目是结合J-lab等几个国际大科学装置的近期和中长期强子物理实验目标而选定的理论前沿研究课题。项目拟探讨在统一的手征夸克模型框架下系统地研究光子驱动(γN)及介子驱动(πN、KN)的散射过程。通过对γN及πN散射的综合研究，一方面要寻找和确认N(1685)、N(1875)S11、N(1875)D13、N(2060)D15等最近新发现的态，提取它们的性质；另一方面要深入理解N(1535，1650)S11、N(1700)D13、N(1720，1900)P13, Δ(1600,1920)P33等已熟知但尚存争议的态的性质，发展和完善非奇异重子谱。 通过对KN散射的研究，一要深入认识Λ(1405，1670)、Λ(1520)等已经建立但长期有争议的超子共振态的性质；另外还要重点寻找尚未建立起来的一系列共振态Σ(1560, 1580, 1620, 1670)，理解它们的性质，发展和完善超子谱。

This program focuses on the hot topics of hadron phsyics at several large experimental facilities, such as J-lab, Spring-8, J-PARC. It aims to solve some important theoretical problems in baryon excitations. This program is to study the photon- and meson-induced reactions with a unified approach (i.e., chiral quark model), where we will derive the properties of baryon resonances, look for missing resonances, etc. By carrying out a combined investigation of the photon- and pion meson- induced reactions, on the one hand we will look for the newly found and unestablished nucleon and Δ resonances, such as N(1685), N(1875)S11, N(1875)D13 and N(2060)D15, and understand their properties. On the other hand we will further clarify some puzzles existing in the well-known resonances N(1535,1650)S11, N(1700)D13, N(1720,1900)P13, Δ(1600,1920)P33. By the study of the kaon meson induced reactions, on the one hand we will further understand the properties of Λ(1405,1670)S01、and Λ(1520)D03. Furthermore, we will look for the unestablished resonances Σ(1560, 1580, 1620, 1670) and derive their properties.
