AbstractAbstract
[en] The polarized longitudinal-transverse structure function σLT' has been measured for the first time in the Δ(1232) resonance region at Q2 = 0.40 and 0.65 GeV2. Data for the p(rvec 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. Evidence for interference between resonant and non-resonant amplitudes is discussed 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
