Findings

Coulomb and three-nucleon forces significantly affect scattering observables.

Renormalization is necessary for accurate scattering amplitude calculations.

The method effectively incorporates complex interactions in three-nucleon systems.

Abstract

Three-nucleon scattering equations with irreducible three-nucleon force are solved in momentum-space. The Coulomb interaction between the two protons is included using the method of screening and renormalization. The need for the renormalization of the scattering amplitudes is demonstrated numerically. The Coulomb and Urbana IX three-nucleon force effects on the observables of elastic proton-deuteron scattering and breakup are studied.
