Sensitivity of Beam-Target Polarized Response Functions in Elastic Electron–Deuteron Scattering to Nucleon Structure and Modern N N Potentials

Аннотация

Polarized response functions for beam and target polarization in the elastic electron-deuteron scattering process are investigated. We report numerical results for all the non-vanishing polarized response functions as functions of the four-momentum transfer square Q². The sensitivity of the predicted results to the nucleon form factors is investigated. For the neutron and proton form factors, the standard dipole fit, the modified dipole fit 1, the modified dipole fit 2, and the relativistic harmonic oscillator model are used. In addition, the dependence of the results on the deuteron wave functions obtained from different modern N N potentials is studied. For this purpose, the realistic and high-precision Argonne υ18, chiral N³LO, Nijmegen-I, and CD-Bonn N N potentials are used. We found that all the non-vanishing polarized response functions are sensitive to the choices of nucleon form factors, whereas they are slightly dependent on the N N potential model adopted for the deuteron wave function. The results for all polarized response functions using the relativistic harmonic oscillator model for the nucleon form factors are found to be very small in comparison to the results of other models.
