Abstract

The H-1(e, e'K+)Lambda reaction was studied as a function of the squar ed four-momentum transfer, Q(2), and the virtual photon polarization, epsilon. For each of four Q(2) settings, 0.52, 0.75, 1.00, and 2.00 (G eV/c)(2), the longitudinal and transverse virtual photon cross section s were extracted in measurements at three virtual photon polarizations . The Q(2) dependence of the sigma(L)/sigma(T) ratio differs significa ntly from current theoretical predictions. This, combined with the pre cision of the measurement, implies a need for revision of existing cal culations.
