The polarization correlation parameter Cnn in the elastic proton-proton scattering was for the first time measured with a high statistical accuracy at 1 GeV using an unpolarized proton beam incident on an unpolarized proton target. Both outgoing prot

We report the first observation of two Cabibbo-suppressed decay modes, Ξ c + → Σ + π − π + and Ξ c + → Σ − π + π + . We observe 59 ± 14 over a background of 87, and 22 ± 8 over a background of 13 events, respectively, for the signal

The polarization of secondary protons from the (p, 2p) reaction induced by 1-GeV protons incident to a 4He nucleus was measured in a kinematically complete experiment. By using a two-arm magnetic spectrometer, two secondary protons from this reaction

Coherent Λπ− production on Pb of 600 GeV Σ− hyperons has been studied with the SELEX facility at Fermilab. Using the Primakoff formalism, we set a 90% CL upper limit on the radiative decay width Γ[Σ(1385)−→Σ−γ] s ≈1.385 GeV to be 5
