  "abstract": "We present a particle-level study of photon-induced production in Herwig 7, focusing on coherent, single-dissociative and double-dissociative proton configurations. The simulation combines the Budnev elastic photon flux with an inelastic photon PDF and uses internal Herwig 7 matrix elements for $γγ\\to \\ell^+\\ell^-$ and $γγ\\to W^+W^-\\to \\ell^+\\ell^-ν\\barν$ as the central setup. Using a dedicated Rivet analysis, we compare hard-system kinematics, charged-particle activity, rapidity-gap observables and forward-remnant-sensitive distributions. We find that shower-setting changes generally have modest effects on hard-system distributions in well-populated regions, while coherent and dissociative samples differ most clearly in additional charged activity and rapidity-gap observables. These results provide a useful baseline for modelling semi-exclusive photon-induced measurements at the LHC and identify the observables most sensitive to dissociative activity in future generator comparisons.",
