DOIAbstract
The reaction pp -> K+ + (Lambda p) has been measured at T-p = 1.953 GeV and Theta = 0 degrees with a high missing-mass resolution in order to study the Lambda p final state interaction. 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
