Abstract

We report the first measurement of differential and total cross sections for the \ud γ\ud d\ud →\ud K\ud 0\ud Λ\ud (\ud p\ud )\ud reaction, using data from the CLAS detector at the Thomas Jefferson National Accelerator Facility. Data collected during two separate experimental runs were studied with photon-energy coverage 0.8–3.6 GeV and 0.5– 2.6 GeV, respectively. The two measurements are consistent giving confidence in the method and determination of systematic uncertainties. The cross sections are compared with predictions from the KAON-MAID theoretical model (without kaon exchange), which deviate from the data at higher \ud W\ud and at forward kaon angles. These data, along with previously published cross sections for \ud K\ud +\ud Λ\ud photoproduction, provide essential constraints on the nucleon resonance spectrum. A first partial wave analysis was performed that describes the data without the introduction of new resonances.
