Abstract: The interaction kernels between vector mesons and octet baryons are calculated explicitly with a summation of t-, s-, u- channel diagrams and a contact term originating from the tensor interaction.Many resonances are generated dynamically in different channels of strangeness zero by solving the coupled-channel Lippman-Schwinger equations with the method of partial wave analysis, and their total angular momenta are determined. The spin partners N(1650)1/2− and N(1700)3/2−, N(1895)1/2− and N(1875)3/2−, and the state N(2120)3/2− are all produced respectively in the isospin I =1/2 sector. In the isospin I =3/2 sector, the spin partners Δ(1620)1/2− and Δ(1700)3/2− are also associated with the pole in the complex energy plane. According to the calculation results, a JP =1/2− state around 2 000 MeV is predicted as the spin partner of N(2120)3/2−.
