| 概要 | A search for the circle minus(+) pentaquark in the K(+)p -> pi X+ reaction was performed utilizing a high-resolution spectrometer at the K6 beam line of the KEK 12GeV Proton Synchrotron. Incident K+ beams of 1.2 GeV/c were irradiated to a liquid hydrogen target. No significant evidence of the circle minus(+) was found. The upper limit of the differential cross section averaged over 2 degrees to 20 degrees in the laboratory frame for the K(+)p -> pi(+)circle minus(+) reaction was obtained to be 1.9 mu b/sr at 90% confidence level. From the present result, the t-channel process is excluded or the coupling constant gK*N circle minus is quite small. |
