Abstract

We present preliminary results of a 2+1-flavor study of finite-volume effects in the lattice QCD computation of the leading-order hadronic contribution to the muon anomalous magnetic moment. We also present methods for obtaining directly the invariant hadronic polarization function, $\Pi(Q^2)$ , and the Adler function at all discrete lattice values of $Q^2$ , including $Q^2=0$ . Results are obtained with HEX-smeared clover fermions.
