We extend the study performed in [V. P. Gonçalves , Phys. Rev. D 102, 074014 (2020).] which has demonstrated that the sum of two semiexclusive tt¯ production modes, namely in photon-Pomeron (γP) and Pomeron-Pomeron (PP) interactions, can be experimentally measured when the tt¯ system decays semileptonically, tt¯→jjblνlb¯, both forward protons are tagged and a low amount of pile-up is present. In this study we focus on separating individual channels and a special attention is paid to the situation at high-luminosity LHC environment. We observe that the separation of the PP and γγ events is a challenging task, especially at high amounts of pile-up even with an optimistic 10 ps resolution of timing detectors.
