Abstract
The study of the properties of the nucleon and nucleon resonances is an important field in the high and intermediate energy nuclear physics, however, until now, our understanding about the structure of the nucleon and nucleon resonances is still in its infancy. We give a brief review on the current researches of the nucleon and nucleon resonances, and point out that the classical quark model can not successfully describe the structure of the nucleon and nucleon resonances. For doing this, a new idea claims that although the five-quark state does not exist, but, there could be significant five-quark components in the nucleon and nucleon resonances.This five-quark configure gives different predictions for the nucleon resonances which will be tested by the future experiments. Now, the proposed Electron-Ion Collider (EIC) will be the most important accelerator installation for studying the nucleon structure, and it is called ”super-electronic-microscope”. Because of the high energy and luminosity, and also low background, we can study the properties of the nucleon and nucleon resonances and new hadron states on EIC.
