【 摘 要 】

Jefferson Lab Experiment E93-018 measured kaon electroproduction in hydrogen in two hyperon channels, p(e, e'K(sup+))Lambda and p(e,e'K(sup+))Sigma(sup 0). Data in both channels were taken at three (3) different values of the virtual photon transverse linear polarization, epsilon, for each of four (4) values of Q(sup 2)= (0.52, 0.75, 1.00, 2.00) GeV(sup 2). Cross sections averaged over the azimuthal angle, phi, were extracted (i.e., sigma(sub T)+ epsilon sigma(sub L)) at each of these twelve points for each hyperon. Rosenbluth separations were performed to separate the longitudinal and transverse production cross sections.
