Backward electroproduction of pi0 mesons on protons in the region of nucleon resonances at four momentum transfer squared Q2 = 1.0 GeV2
Description
Exclusive electroproduction of pi0 mesons on protons in the backward hemisphere has been studied at Q2 = 1.0 GeV2 by detecting protons in the forward direction in coincidence with scattered electrons from the 4 GeV electron beam in Jefferson Lab's Hall A. The data span the range of the total (gamma*p) center-of-mass energy W from the pion production threshold to W 2.0 GeV. The differential cross sections sigmaT + epsilon sigmaL, sigmaTL, and sigmaTT were separated from the azimuthal distribution and are presented together with the MAID and SAID parameterizations
