Abstract

We report measurements of the exclusive electroproduction of K+Lambda and K+Sigma(0) final states from an unpolarized proton target using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The separated structure functions sigma(U), sigma(LT), sigma(T) T, and sigma(LT') were extracted from the Phi-dependent differential cross sections acquired with a longitudinally polarized 5.499 GeV electron beam. The data span a broad range of momentum transfers Q(2) from 1.4 to 3.9GeV(2), invariant energy W from threshold to 2.6GeV, and nearly the full center-of-mass angular range of the kaon. The separated structure functions provide an unprecedented data sample, which, in conjunction with other meson photo-and electroproduction data, will help to constrain the higher-level analyses being performed to search for missing baryon resonances.
