SU(2)_F bosons in a U(2)_F flavor model induce unsuppressed flavor-violating couplings, with K to pi X and mu to e X constraining the breaking scale v_phi to 10^11-10^12 GeV for light bosons and other processes constraining heavier states.

Above the muon threshold, LFV ALP production in K, D_s, W, Z, J/ψ and τ decays gives new prompt and displaced search channels with projected reach up to f_a ≈ 10^8 GeV.
This work provides a comprehensive analysis of light new physics contributions to tau lepton dipole moments, detailing interpretations of asymmetry measurements for spin-0 and spin-1 bosons, their decoupling to the EFT limit, and a case study of a tauphilic vector boson at Belle II.
In a simplified ALP model with flavor-violating e-μ couplings, constraints from Δa_e, μ→3e, and other processes limit the branching ratio of μ⁻e⁻→e⁻e⁻ in aluminum muonic atoms to O(10^{-20}), with resonant regions more suppressed.
A minimal electrophilic ALP portal for SIMP pion dark matter widens the allowed parameter space, making an ALP mass of order 10 MeV viable and consistent with the X17 anomaly.
Review surveying limits and prospects for flavor-violating decays of light axion-like particles, highlighting complementarity of lab, astro, and cosmo probes up to 10^12 GeV scales.
