被引用回数:0 パーセンタイル:0(Physics, Multidisciplinary)In this work, we outline the findings of our recent study of the properties of and its consequential impacts on the cross-sections of the photoproduction of (1405). Further, we discuss the possibility of the existence of an isovector state with a mass similar to (1405), which we refer to as (1400). With the idea of motivating experimental investigations of (1400), we have studied its photo-production process and determined the respective cross-sections and polarization observables. We have studied also the coupling of to (1400) and found that it gives an important contribution to the cross-sections near the threshold. In the process, we have determined the branching ratios of the decay of to the final states involving (1405) and (1400) to be in the range of 6-7 MeV. Our findings can motivate the consideration of alternative processes in partial wave analyses of experimental data when studying the properties of .
