Measurement of the differential cross sections of the Σ−p elastic scattering in momentum range 470 to 850 MeV/c
Popis: | International audience; A high statistics Σp scattering experiment is performed at the J-PARC Hadron Experimental Facility. Momentum-tagged Σ−s running in a liquid hydrogen target are accumulated by detecting the π−p→K+Σ− reaction with a high intensity π− beam of 20 M/spill. The differential cross sections of the Σ−p elastic scattering were derived with a drastically improved accuracy by identifying approximately 4500 events from 1.72×107Σ−. The derived differential cross section shows a clear forward-peaking angular distribution for a Σ− 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. |
