The pentaquark baryon was searched for via the reaction in a missing-mass resolution of 1.4 MeV/ (FWHM) at J-PARC. meson beams were incident on the liquid hydrogen target with the beam momentum of 1.92 GeV/. No peak structure corresponding to the mass was observed. The upper limit of the production cross section averaged over the scattering angle of 2 to 15 in the laboratory frame was obtained to be 0.26 b/sr in the mass region of 1.511.55 GeV/. The upper limit of the decay width using the effective Lagrangian approach was obtained to be 0.72 MeV/ and 3.1 MeV/ for and , respectively.
