Abstract (data abstract)
Jefferson Lab - CEBAF. Measurements of the exclusive electroproduction of K+ LAMBDA and K+ SIGMA0 final states from a proton target using electron beams of energy 2.567, 4.056 and 4.247 GeV. The data from the latter two energies are combined into one set, called here 4 GeV. The separated structure functions SIG(T), SIG(L), SIG(TT) and SIG(LL) are extracted from the PHI and EPSILON dependence of the differential cross sections. The 2.567 GeV data set has an integrated luminosity of 1.32 FB-1 and the 4.056 and 4.247 GeV data sets have respectively 0.67 and 0.80 FB-1. The data covers the Q**2 range from 0.5 to 2.8 GeV**2 and the W range from 1.6 to 2.4 GeV and spans almost the complete centre-of-mass angular range of theJK+. The data are taken from the CLAS online database.. This part (1) contains the SIG, SIG(TT) and SIG(LL) cross sections for the K+ LAMBDA 2.57 and 4 Gev data. Jefferson Lab - CEBAF.
