We present a combined QCD analysis of recent data produced by the H1 and ZEUS Collaborations on the diffractive and leading-proton deep inelastic positron-proton scattering structure functions FD2 and FL2P , respectively. It is shown that the QCD framework for semi-inclusive processes, based on fracture functions, allows a unified treatment of both diffractive and leading-proton processes, and offers a precise perturbative QCD description for them, alternative to those that rely on model-dependent assumptions, such as Regge factorization, or other nonperturbative approaches.
