Narrow S=-1 resonances predicted by bag model calculations are not visible in the missing-mass spectrum. Small structures observed in a previous experiment are not confirmed. Upper limits for the production cross section of a narrow resonance are deduced for missing masses between 2058 and 2105 MeV.en©2011 American Physical SocietyUpper limits for a narrow resonance in the reaction p + p → Κ⁺ + (Λp)Upper limits for a narrow resonance in the reaction p + p -> Kappa(+) + (Lambda p)Journal article002011168810.1103/PhysRevD.84.032002000293556300002
