	Abstract	We analyze the proton-box contribution to the hadronic light-by-light part of the muon's anomalous magnetic moment, which is the first reported baryonic contribution to this piece. We follow the quark-loop analysis, incorporating the relevant data-driven and lattice proton form factors. Although the heavy mass expansion would yield a contribution of O & eth;10-10 & THORN;, the damping of the form factors in the regions where the kernel peaks explains our finding μap-box 1/4 1.82 & eth;7 & THORN; x 10-12, 2 orders of magnitude smaller than the forthcoming uncertainty on the a μmeasurement and on its Standard Model prediction.
