DOIAbstract
International audienceWe present precision measurements of the target and beam-target spin asymmetries from neutral pion electroproduction in deep-inelastic scattering (DIS) using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. We scattered 6-GeV, longitudinally polarized electrons off longitudinally polarized protons in a cryogenic 14 NH 3 target, and extracted double and single target spin asymmetries for ep→e′π0X in multidimensional bins in four-momentum transfer ( 1.0<Q2<3.2 GeV 2 ), Bjorken- x ( 0.12<x<0.48 ), hadron energy fraction ( 0.4<z<0.7 ), transverse pion momentum ( 0<PT<1.0 GeV), and azimuthal angle ϕh between the lepton scattering and hadron production planes. We extracted asymmetries as a function of both x ...
