Description

We report on the HPQCD calculation of the u/d HVP contribution to a_mu, discussed in arXiv:1601.03071. This allows us to obtain a total HVP contribution from u, d, s and c quarks and including an estimate of disconnected pieces and QED and isospin effects of 666(6)(12) x 10^{-10}. Our result implies a discrepancy between the experimental determination of a_mu and the Standard Model of 3 sigma. We discuss prospects for improvements to this calculation underway with the MILC and Fermilab Lattice Collaborations.
