Description
In this talk I will show how an ultra light dark matter background affects the electron g-2 value. The effect comes from an enhancement in the triangle diagram due to the high occupancy number of a boson field with a very low mass. The results are immediately used to put strong constraints on axion-electron couplings and dark photon kinetic mixing parameters, for masses below $10^{-15}$ eV.
