Central Exclusive Production Measurements in the LHCb

Central Exclusive Production (CEP) is a class of diffractive processes studied at the Large Hadron Collider, that offers a very clean experimental environment for probing the low-energy regime of Quantum Chromodynamics and testing the Standard Model predictions. The paper summarizes the CEP analyses conducted by the LHCb Collaboration. The latest measurements of $J/ \psi$ and $\psi (2S)$ photoproduction are discussed, along with the impact of the HeRSCheL detector on dissociation background reduction. Finally, a novel Monte Carlo event generator for diffractive physics is presented as a work-in-progress project.
