The internal structures of the nucleon resonances $N(1875)$ and $N(2120)$

Abstract

A nucleon resonance with spin-parity $J^P=3/2^{-}$ and mass about 2.1 GeV is essential to reproduce the photoproduction cross sections for $\Lambda (1520)$ released by the LEPS and CLAS Collaborations. It can be explained as the third nucleon resonance state $[3/2^{-}{]}_3$ in the constituent quark model so that there is no position to settle the $N(1875)$ which is listed in the PDG as the third $N3/2^{-}$ nucleon resonance. An interpretation is proposed that the $N(1875)$ is from the interaction of a decuplet baryon $\Sigma (1385)$ and a octet meson $K$, which is favored by a calculation of binding energy and decay pattern in a Bethe-Salpeter approach.
