Resumo

We report measurements of cross sections for the reaction 1H(e,e′K+)Y, for both the Λ and Σ0 hyperon states, at an invariant mass of W=1.84GeV and four-momentum transfers 0.5<Q2<2(GeV/c)2. Data were taken for three values of virtual photon polarization ε, allowing the decomposition of the cross sections into longitudinal and transverse components. The Λ data are a revised analysis of prior work, whereas the Σ0 results have not been previously reported.Received 5 November 2002DOI:https://doi.org/10.1103/PhysRevC.67.055205©2003 American Physical Society
