Thepentaquark baryon was searched for via thereaction with a missing mass resolution of(FWHM) at the Japan Proton Accelerator Research Complex (J-PARC).meson beams were incident on the liquid hydrogen target with a beam momentum of. No peak structure corresponding to themass was observed. The upper limit of the production cross section averaged over the scattering angle of 2° to 15° in the laboratory frame is obtained to bein the mass region of. The upper limit of thedecay width is obtained to be 0.72 and 3.1 MeV forand, respectively, using the effective Lagrangian approach.
