Measurement of the deuteron elastic structure functions at large momentum transfers
- Old Dominion Univ., Norfolk, VA (United States)
The cross section for elastic electron-deuteron scattering has been measured using the Hall A Facility of Jefferson Laboratory. Scattered electrons and recoiling deuterons were detected in coincidence in the two 4 GeV/c High Resolution Spectrometers (HRS) of Hall A. The deuteron elastic structure functions A(Q2) and B(Q2) have been extracted from these data. Results for the measurement of A(Q2) in the range of 0.7 ≤ Q2 ≤ 6.0 (GeV/c)2 are reported. Results for the magnetic structure function, B(Q2), are presented in the range of 0.7 ≤ Q2≤ 1.35 (GeV/c)2. The results for both structure functions are compared to predictions of meson-nucleon based models, both with and without the inclusion of meson-exchange currents. The A(Q2) results are compared to predictions of the dimensional scaling quark model and perturbative quantum chromodynamics. The results can provide insights into the transition from meson-nucleon to quark-gluon descriptions of the nuclear two-body system.
