Longitudinal and Transverse Cross Sections in the 1H(E, E'K+)Λ Reaction
Abstract
The 1H(e,e'K+)Λ reaction was studied as a function of the squared four-momentum-transfer, Q2, and the virtual photon polarization, ɛ. For each of four Q2 settings, from 0.5 to 2.0 (GeV/c)2, the longitudinal and transverse virtual photon cross sections were extracted in measurements at three virtual photon polarizations. The σL/σT ratio is found to have a Q2 dependence that differs from existing theoretical predictions.
