Bounds on hadronic contributions to the anomalous magnetic moment of the $τ$ 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 $τ$ lepton ($a_τ…

Bottom-Charm $[b c]$ Diquark Masses from QCD Laplace Sum-Rules

T. de Oliveira, D. Harnett, J. Ho +5

Constituent mass predictions for bottom-charm $[b c]$ color-antitriplet diquarks are generated using QCD Laplace sum rules. We calculate the diquark correlator within the operator p…

Lepton $g - 2$ non-universality of hadronic contributions and a sub-GeV window to New Physics

Siyuan Li, Vladimir Pascalutsa, Maxim Pospelov

We propose the linear combination of the anomalous magnetic moments of the muon and electron, $a_{μ - e} \equiv a_{μ} - (m_{μ} / m_{e})^{2} a_{e}$ , as a natural low-energy window quantity that ma…
