Abstract: We show the outstanding potential of the High-Luminosity LHC (HL-LHC) to discover charged lepton flavor violation (cLFV) via the ultraperipheral process γ γ → e ± μ ∓ . Using a gauge-invariant effective field theory framework—consistent with the most stringent bounds from radiative decays—we perform a full Monte Carlo analysis with multivariate techniques. Our results show that a 5 σ discovery is achievable with an integrated luminosity of L int ≳ 2700 fb − 1 for favorable benchmark scenarios. This study establishes photon fusion at the HL-LHC as a powerful probe of cLFV, strongly motivating dedicated searches by the experimental collaborations.
