Abstract

We have carried out a pilot data taking of the J-PARC E05 experiment to search for the bound state peaks of ¹²_Ξ Be in the ¹²C(K^-,K⁺)X reaction at 1.8 GeV/c. The measurement was performed at the K1.8 beam line of the J-PARC hadron experimental hall with a typical K^- beam intensity of 6×10⁵ every six seconds. So far the best energy resolution of about 6 MeV_FWHM was achieved with the existing SKS spectrometer. With a reasonable statistics, we have succeeded to observe peak structures in the bound region, which seems to suggest that the potential depth of Ξ would be deeper than 14 MeV estimated in the previous measurements.
