A high statistics ∑p scattering experiment has been performed at the K1.8 beamline in the J-PARC Hadron Experimental Facility. Data for momentum-tagged ∑- beam running in a liquid hydrogen target were accumulated by detecting the reaction with a high intensity π- beam of 20 M/spill. The number of the Σ- beam was about 1.7 107 in total. The ∑-ρ elastic scattering and the ∑-p → Λn inelastic scattering events were successfully observed with about 100 times larger statistics than that in past experiments.
