In about a third of proton-proton collisions in the Large Hadron Collider (LHC) at least one of the interacting protons survives and scatters to a very small angle. Detecting such forward protons extends the event characterisation and thus the LHC physics programme. Most often, the events with a surviving proton(s) are associated with low momentum transfer between the interacting protons (e.g. elastic or diffractive scattering). This corresponds to the nonperturbative regime of Quantum Chromodynamics (QCD), where first-principle theoretical predictions are difficult to obtain and largely...
