Abstract

The polarized longitudinal-transverse structure function σ _LT′ has been measured in the Δ(1232) resonance region at Q² = 0.40 and 0.65 GeV². Data for the p(e ^→,e′p) π⁰ reaction were taken at Jefferson Lab with the CEBAF large acceptance spectrometer (CLAS) using longitudinally polarized electrons at an energy of 1.515 GeV. For the first time a complete angular distribution was measured, permitting the separation of different nonresonant amplitudes using a partial wave analysis. Comparison with previous beam asymmetry measurements at MAMI indicate a deviation from the predicted Q² dependence of σ_LT′ using recent phenomenological models.

N2 - The polarized longitudinal-transverse structure function σ LT′ has been measured in the Δ(1232) resonance region at Q2 = 0.40 and 0.65 GeV2. Data for the p(e →,e′p) π0 reaction were taken at Jefferson Lab with the CEBAF large acceptance spectrometer (CLAS) using longitudinally polarized electrons at an energy of 1.515 GeV. For the first time a complete angular distribution was measured, permitting the separation of different nonresonant amplitudes using a partial wave analysis. Comparison with previous beam asymmetry measurements at MAMI indicate a deviation from the predicted Q2 dependence of σLT′ using recent phenomenological models.
