| Coupling constants of the S11 resonances to pseudoscalar mesons and octet baryons (arXiv: 1107.5991) |
| C. S. An, B. Saghai |
| Coupling constants of S11(1535) and S11(1650) resonances to meson-baryon (piN, etaN, eta′N, KY) are investigated in a chiral quark model, complemented by inclusion of five-quark components in those resonances. The known strong decay partial widths of both resonances are well reproduced, provided sizeable strangeness components in the relevant wave functions. |
