英文摘要In this report we investigate eta-meson productions oil the proton via electromagnetic and hadron probes in a chiral quark model approach. The observables, such as, differential cross section and beam asymmetry for the two productions are calculated and compared with the experiment. The five known resonances S(11)(1535) S(11)(1650); P(13)(1720) D(13)(1520), and F(15)(1680) are found to be dominant in the reaction mech-anisms in both channels. Significant, contribution from a new S(11) resonances are deduced. For the so-called "missing resonances", no evidence is found within the investigated reactions. The partial wave amplitudes for pi(-)p -> eta n are also presented.
