- Abstract
- A high statistics Sigma p scattering experiment is performed at the J-PARC Hadron Experimental Facility. Momentum-tagged Sigma(-)s running in a liquid hydrogen target are accumulated by detecting the pi(-)p -> K+Sigma(-) reaction with a high intensity ir- beam of 20 M/spill. The differential cross sections of the Sigma(-) p elastic scattering were derived with a drastically improved accuracy by identifying approximately 4500 events from 1.72x10(7) Sigma(-). The derived differential cross section shows a clear forward-peaking angular distribution for a E- momentum range from 470 to 850 MeV/c. The accurate data will impose a strong constraint on the theoretical models of the baryon-baryon interactions.
