The Coulomb interaction between the two protons is included in thecalculation of proton-deuteron breakup and of three-body electromagneticdisintegration of ${}^3\mathrm{He}$. The hadron dynamics is based on the purelynucleonic charge-dependent (CD) Bonn potential and its realistic extension CDBonn + $\Delta$ to a coupled-channel two-baryon potential, allowing for singlevirtual $\Delta$-isobar excitation. Calculations are done using integralequations in momentum space. The screening and renormalization approach isemployed for including the Coulomb interaction. Convergence of the procedure isfound at moderate screening radii. The reliability of the method isdemonstrated. The Coulomb effect on breakup observables is seen at all energiesin particular kinematic regimes.Comment: Corrected errors in Figs. 2, 10 - 1
