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, $a_{I^¼ - e} \equiv a_{I^} ¼ - (m_{I^} ¼/ m_{e})^{2} a_{e}$ , as a natural low-energy window quantity that…

An Application of Diagrammatic Renormalization to $2^{++}$ Tensor Di-Gluonium

T. de Oliveira, Siyuan Li, T. G. Steele

We apply the diagrammatic renormalization method to the NLO analysis of the $2^{++}$ tensor di-gluonium channel within the QCD sum-rules approach. Diagrammatic renormalization elim…

$2^{++}$ Di-gluonium from LSR at higher order

Siyuan Li, Stephan Narison, Davidson Rabetiarivony +1

We improve the determination of the mass and coupling of the $2^{++}$ tensor di-gluonium by using relativistic QCD Laplace sum rules (LSR). In so doing, we evaluate the next-to-lea…
