摘要

A search for an S=+1 baryon resonances in the K- missing-mass spectrum of the γn→K+K-n reaction on 12C, using a newly built photon-beam facility at the SPring-8. As such, a sharp baryon resonance peak was found at 1.54±0.01 GeV/c2 in the K- missing-mass spectrum that was corrected for the Fermi motion. It was indicated that the existence of an S=+1 resonance which may be attributed to the molecular meson-baryon resonance or alternatively as an exotic five-quark baryon proposed as the Z+.
