“…Thus, our three-particle equations, including the screened Coulomb potential, are completely different from the quasiparticle equations solved in Ref. [6] where the two-nucleon screened Coulomb transition matrix is approximated by the screened Coulomb potential. In Ref.…”

“…According to Refs. [6,11], the full breakup transition amplitude for initial and final states |φ α (q i )ν αi and |φ…”

“…We prefer to work with a sharper screening than the Yukawa screening (n = 1) of Ref. [6]. We want to ensure that the screened Coulomb potential w R approximates well the true Coulomb one w for distances r < R and simultaneously vanishes rapidly for r > R, providing a comparatively fast convergence of the partial-wave expansion.…”

“…Whereas it has already been solved for elastic proton-deuteron (pd) scattering with realistic hadronic interactions using various procedures [1,2,3,4,5], there are only very few attempts [6,7,8] to calculate pd breakup, and none of them uses a complete treatment of the Coulomb interaction and realistic hadronic potentials allowing for a stringent comparison with the experimental data.…”

“…In that extension we follow the ideas of Refs. [6,10,11], but avoid approximations on the hadronic potential and in the treatment of screened Coulomb. Thus, our three-particle equations, including the screened Coulomb potential, are completely different from the quasiparticle equations solved in Ref.…”
