      abstract     = {The first FASER search for a light, long-lived particle
                      decaying into a pair of photons is reported. The search uses
                      LHC proton-proton collision data at $ \sqrt{s} $ = 13.6 TeV
                      collected in 2022 and 2023, corresponding to an integrated
                      luminosity of 57.7 fb$^{−1}$. A model with axion-like
                      particles (ALPs) dominantly coupled to weak gauge bosons is
                      the primary target. Signal events are characterised by
                      high-energy deposits in the electromagnetic calorimeter and
                      no signal in the veto scintillators. One event is observed,
                      compared to a background expectation of 0.44 ± 0.39 events,
                      which is entirely dominated by neutrino interactions.
                      World-leading constraints on ALPs are obtained for masses up
                      to 300 MeV and couplings to the Standard Model W gauge
                      boson, g$_{aWW}$, around 10$^{−4}$ GeV$^{−1}$, testing a
                      previously unexplored region of parameter space. Other new
                      particle models that lead to the same experimental
                      signature, including ALPs coupled to gluons or photons,
                      U(1)$_{B}$ gauge bosons, up-philic scalars, and a Type-I
                      two-Higgs doublet model, are also considered for
                      interpretation, and new constraints on previously viable
                      parameter space are presented in this paper.[graphic not
