Polarization observables in $p-d$ scattering below 30 MeV

Differential and total breakup cross sections as well as vector and tensor analyzing powers for $p-d$ scattering are studied for energies above the deuteron breakup threshold up to $E_{\mathrm{lab}}=28\mathrm{}\hspace{0.5em}\mathrm{MeV}.$ The $p-d$ scattering wave function is expanded in terms of the correlated hyperspherical harmonic basis and the elastic S matrix is obtained using the Kohn variational principle in its complex form. The effects of the Coulomb interaction, which are expected to be important in this energy range, have been rigorously taken into account. The Argonne AV18 interaction and the Urbana URIX three-nucleon potential have been used to perform a comparison to the available experimental data.
