Abstract

Exclusive electroproduction of π⁰ 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 (γ*p) center-of-mass energy W from the pion production threshold to W=2.0 GeV. The differential cross sections σ_T+ εσ_L, σ_TL, and σ_TT were separated from the azimuthal distribution and are presented together with the MAID and SAID parametrizations.

N2 - Exclusive electroproduction of π0 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 (γ*p) center-of-mass energy W from the pion production threshold to W=2.0 GeV. The differential cross sections σT+ εσL, σTL, and σTT were separated from the azimuthal distribution and are presented together with the MAID and SAID parametrizations.
