Title Cross Sections and Rosenbluth Separations from Kaon Electroproduction on Protons upto Q2=2.35 (GeV/c)2
Abstract The kaon electroproduction reaction H( e, e ' K + )? was studied as a function of the four momentum transfer, Q 2 , for different values of the virtual photon polarization parameter. Electrons and kaons were detected in coincidence in two High Resolution Spectrometers (HRS) at Jefferson Lab. Data were taken at electron beam energies ranging from 3.4006 to 5.7544 GeV. The kaons were identified using combined time of flight information and two Aerogel Cerenkov detectors used for particle identification. For different values of Q 2 ranging from 1.90 to 2.35 GeV/c 2 the center of mass cross sections for the ? hyperon were determined for 20 kinematics and the longitudinal, ? L , and transverse, ? T , terms were separated using the Rosenbluth separation technique. Comparisons between available models and data have been studied. The comparison supports the t-channel dominance behavior for kaon electroproduction. All models seem to underpredict the transverse cross section.
