We propose a new set of model independent approximants adapted to the time momentum representation (TMR) of hadronic vacuum polarization (HVP) and its contribution to g μ – 2. They provide a way to extrapolate lattice QCD (LQCD) results obtained in an optimal time-region, to the full range required for an evaluation of the HVP contribution to g μ – 2. They offer as well a new way to confront LQCD results in restricted TMR regions, with the full contribution obtained from data driven determinations.
