Description
With recent updates on the experimental measurement of the muon’s anomalous magnetic moment ($a_\mu=\left(g-2\right)_\mu/2$) at Fermilab, the discrepancy between experimental results and Standard Model predictions is heightened to $5.0\sigma$. Along with the dependencies between the theoretical predictions from lattice QCD and data-driven methods, we establish upper and lower bounds for the hadronic vacuum polarization (HVP) contribution to the leading-order (LO) muon’s anomalous magnetic moment ($a_\mu^\text{HVP,LO}$) using the finite-energy QCD sum-rules (FESR) and H\"older inequalities.
Our results are evaluated up to five-loop order in perturbation theory in the chiral limit, LO in light-quark mass corrections, next-to-leading order in dimension-four QCD condensates, and LO in dimension-six QCD condensates, offering a path toward resolving the current tension in future investigations of the muon’s anomalous magnetic moment.
