(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) Issue Title: FB20 Proceedings Within an effective Lagrangian approach, we investigate the reaction mechanism of K ^sup -^ p [arrow right] [eta][Lambda] near threshold. It is found that a new D ^sub 03^ resonance, with mass M = 1,668.5 ± 0.5 MeV and width [Gamma] = 1.5 ± 0.5 MeV, is needed to interpret the experimental data reported by the Crystal Ball collaboration. To verify our results, remeasurements on the differential cross sections and [Lambda] polarization in this reaction will be helpful. Furthermore, we also show that the reaction ... is a good place to look for this new resonance if it exists.[PUBLICATION ABSTRACT]
