Abstract:
A search for the S(1936) has been made in the invariant mass spectrum of p?p-pairs produced inclusively in proton-beryllium interactions at 100 GeV incident momentum. No enhancement is observed, giving a 3 standard deviation upper limit on the cross section of 220 nb/nucleon for production of a narrow p?p state around ≈ 1940 MeV in the xF range 0.18 <xF<0.48.
