Deuteron form factor measurements at low momentum transfers

Measurements of the deuteron and proton magnetic form factors at large momentum transfers.

_. Measurements of the deuteron elastic magnetic structure function B(Q2) are reported at squared four-momentum transfer values 1.20 5 Q2 < 2.77 (GeV/c)2. Also reported are values for the proton magnetic form factor Gn.lp(Q2) at eleven Q2 values between 0.49 and 1.75 (GeV/c)2. The d t a a were obtained at the Stanford Linear Accelerator Center using the electron beam from the Nuclear Physics In...

Pion Form Factor in QCD at Intermediate Momentum Transfers

We present a quantitative analysis of the electromagnetic pion form factor in the light-cone sum rule approach, including radiative corrections and higher-twist effects. The comparison to the existing data favors the asymptotic profile of the pion distribution amplitude and allows to estimate the deviation: ( ∫ du/uφπ(u))/( ∫ du/uφas π (u)) = 1.1± 0.1 at the scale 1 GeV. Special attention is pa...

Measurements of transverse electron scattering from the deuteron in the threshold region at high momentum transfers.

Measurements of transverse quasielastic electron scattering from the deuteron at high momentum transfers.

Cross sections for 180’ inelastic electron scattering from the deuteron were measured from the break-up threshold to beyond the quasielastic peak for incident beam energies of 0.843, 1.020, 1.189, and 1.281 GeV, corresponding to 0.75 5 Q2 <_ 2.57 (GeV/c)2. Th e d t a a are in reasonable agreement with nonrelativistic models that include final-state interactions and meson exchange currents. The ...

The Deuteron Electromagnetic Form Factor

A vector mesonic correction to the deuteron form factors is considered which is analogous to the Glauber double scattering , process D This correction dominates the form factors at large , momentum transfer 0 A fit to the static magnetic moment of the deuteron yields a satisfactory fit to the magnetic scattering at large momentum transfer.
