Description
We present preliminary results for the (connected) hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment (g-2). The HVP is computed for degenerate up and down quarks at the physical point on HISQ 2+1+1 flavor ensembles generated by the MILC collaboration. We use all mode and low mode averaging with 2000-3000 lowmodes to obtain precise statistics. Calculations performed at three lattice spacings (0.06, 0.09, and 0.12 fm) are used to estimate the continuum limit in finite volume. Chiral perturbation theory is used to estimate the finite volume effect. We compare to other recent results.
