Lightest pseudoscalar (P= pi^0, eta, eta') exchange contribution to thelight-by-light (LbL) scattering piece of the muon anomaly, a_mu=(g_mu-2)/2, hasbeen evaluated using a resonance chiral Lagrangian (R\chi L). Best descriptionof pion transition form-factor (TFF) data is obtained with only tiny violationsof one of the relations in the minimal consistent set of short-distanceconstraints on the anomalous R\chi L couplings. eta^{(')} TFF, predicted interms of the pi TFF and the eta-eta^' mixing, are in good agreement withmeasurements. With this input, we obtain a_mu^{P,LbL} = (10.47\pm0.54)x10^-10,consistent with the reference determinations in the literature, albeit withsmaller error.
