Background: Nucleon-knockout reactions on proton targets (p, pN) have experienced a renewed interest due to the availability of inverse-kinematics experiments with exotic nuclei. Various theoretical descriptions have been used to describe these reactions, such as the distorted-wave impulse approximation, the Faddeev-type formalism, and the transfer-to-the-continuum method. Purpose: Our goal is to benchmark the observables computed with the Faddeev and transfer-to-the-continuum formalisms in the intermediate energy regime relevant for the experimental (p, pn) and (p, 2p) studies. Method: We analyze the Be-11(p, pn) Be-10 reaction for different beam energies, binding energies, and orbital quantum numbers with both formalisms to assess their agreement for different observables. Results: We obtain a good agreement in all cases considered, within approximate to 10%, when the input potentials are taken consistently and realistically. Conclusions: The results of this work prove the consistency and accuracy of both methods, setting an indication on the degree of systematic uncertainties applicable when using them to extract spectroscopic information from (p, pN) reactions.
