Abstract

The polarized longitudinal-transverse structure function sigma(LT') has been measured in the Delta(1232) resonance region at Q(2)=0.40 and 0.65 GeV2. Data for the p((e) over right arrow ,e'p)pi(0) 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 Q(2) dependence of sigma(LT ') using recent phenomenological models.
