Description

We measured the (K, π+) reaction spectra at 1.8 GeV/c for the graphite and the polyethylene targets in the J-PARC E05 pilot experiment. By comparing the spectra for these two targets, it was found that Σ*(1385) in the 11B nucleus is quite broadened. Furthermore, we also compared broadness of Σ*(1385) with K*(892) obtained in the (K, p) spectrum. Σ*(1385) seems to be much more broadened in nuclei than K*(892). We gave a possible interpretation, which is related to compositeness of decuplet baryons, for this situation. (author)
