Combining electron and muon g-2 with the MICROSCOPE equivalence principle test bounds a light scalar's couplings at |λ_e| ≤ 6e-6, |λ_μ| ≤ 3.5e-4, and |λ_γ| ≤ 4.5e-13 eV^-1.
This greatly con- fine the allowed parameter region, which clearly shows the advantage of putting all three experimental results together to constrain the scalar model
