Ratio of \(\sigma_L / \sigma_T\) for \(p(e,e'K^+)\Lambda\) Extracted from Polarization Transfer

The ratio of longitudinal to transverse structure functions, \(\sigma_L/\sigma_T\), has been extracted from recent beam-recoil transferred polarization data for the \(p(\vec e,e'K^+)\vec\Lambda\) reaction. Results have been obtained for \(W\)=1.72, 1.84, and 1.98 GeV at an average \(Q^2\) of 0....

Summary:The ratio of longitudinal to transverse structure functions, \(\sigma_L/\sigma_T\), has been extracted from recent beam-recoil transferred polarization data for the \(p(\vec e,e'K^+)\vec\Lambda\) reaction. Results have been obtained for \(W\)=1.72, 1.84, and 1.98 GeV at an average \(Q^2\) of 0.77, 0.69, and 0.61 GeV\(^2\), respectively. Our results indicate a ratio that is systematically slightly smaller than previously published results using a Rosenbluth separation.
