Abstract

The first measurements of the polarized structure function sigma(')(LT) for the reaction H-1(e,e(')K(+))Lambda in the nucleon resonance region are reported. Measurements are included from threshold up to W=2.05 GeV for central values of Q(2) of 0.65 and 1.00 GeV2, and nearly the entire kaon center-of-mass angular range. sigma(')(LT) is the imaginary part of the longitudinal-transverse response and is expected to be sensitive to interferences between competing intermediate s-channel resonances, as well as resonant and nonresonant processes. The results for sigma(')(LT) are comparable in magnitude to previously reported results from CLAS for sigma(LT), the real part of the same response. An intriguing sign change in sigma(')(LT) is observed in the high Q(2) data at W approximate to 1.9 GeV. Comparisons to several existing model predictions are shown.
