Description
Although being a higher-twist contribution, the transverse response was assumed to be responsible of the large π0 electroproduction cross sections measured by the Hall A and CLAS collaboration. However no Rosenbluth separation has been performed yet to verify this assumption. We will present new results of π0 electroproduction cross sections in the valence region (xBj=0.36) at three Q2 -values (1.5, 1.75 and 2 GeV2). Unlike the previous data sets, each kinematical setting was run with two beam energies. It allows to perform, for the first time, the separation of the longitudinal and transverse contributions.
