    "abstract": "The structure of Omega-pi state with isospin I=1 and spin-parity J^p=3/2^-\nare dynamically studied in both the chiral SU(3) quark model and the extended\nchiral SU(3) quark model by solving a resonating group method (RGM) equation.\nThe model parameters are taken from our previous work, which gave a\nsatisfactory description of the energies of the baryon ground states, the\nbinding energy of the deuteron, the nucleon-nucleon (NN) scattering phase\nshifts, and the hyperon-nucleon (YN) cross sections. The calculated results\nshow that the Omega-pi state has an attractive interaction, and in the extended\nchiral SU(3) quark model such an attraction can make for an Omega-pi\nquasi-bound state with the binding energy of about several MeV.",
