Bounds on hadronic contributions to the anomalous magnetic moment of the $\tau$ lepton from QCD Sum Rules

Siyuan Li, J. Ho, R. T. Kleiv +3

A QCD sum-rule study is performed to place bounds on the leading-order (LO) hadronic vacuum polarization (HVP) contribution to the anomalous magnetic moment of the $\tau$ lepton ($a_τ…
