Title: Strangeness in N(1535)

Keywords: N(1535), strangeness

Abstract:
Here we employ the extended chiral constituent quark model to investigate the five-quark components in the N(1535) resonance. The axial charge of N(1535) and the electromagnetic transition virtual gamma and nucleon to N(1535) are also analyzed. The results show that there may be sizeble strangeness component in N(1535).
