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 12C(p,3p)10Be, 28Mg(p,3p)26Ne and 54Ca(p,3p)52Ar, finding reasonable agreement to experimental data for the 12C target and an overestimation of a factor ∼3 for the more neutron-rich and 54Ca, which is similar to the results found in two-proton knockout experiments with 9Be and 12C targets.
