| contents | In this work, we present the first, to our knowledge, theoretical description of two-proton removal reactions with proton target $(p,3p)$ for medium-mass nuclei at intermediate energies and present cross sections for the different bound states of the residual nucleus with two fewer protons. The description of the reaction assumes two sequential ``quasifree'' collisions between the target and removed protons and considers eikonal propagation in between. The formalism is applied to the reactions $^{12}\mathrm{C}(p,3p)^{10}\mathrm{Be}$, $^{28}\mathrm{Mg}(p,3p)^{26}\mathrm{Ne}$ and $^{54}\mathrm{Ca}(p,3p)^{52}\mathrm{Ar}$, finding reasonable agreement to experimental data for the $^{12}$C target and an overestimation of a factor $\sim3$ for the more neutron-rich and $^{54}$Ca, which is similar to the results found in two-proton knockout experiments with $^9$Be and $^{12}$C targets. |
