$2^{++}$ Light Tensor Hybrid Meson from QCD Laplace Sum Rules

Jason Ho, Robin Kleiv, Siyuan Li +3

We present an analysis of the light tensor ( $J^{P C} = 2^{++}$ ) hybrid meson mass and coupling from QCD Laplace Sum Rules where the next-to-leading order (NLO) perturbative (PT) corre…

Revisiting the Muon Anomaly from $e^{+} e^{-} \to$ Hadrons

Stephan Narison

In this talk, I revisit and present a more comprehensive estimate of the lowest order Hadronic Vacuum Polarization (HVP) contribution $a_{I^} ¼ ∣_{h v p}^{l o}$ to the muon anomalous m…

QCD condensates and $I^\pm_{s}$ from $e^{+} e^{-}$ and $I ¨ $ -decays

Stephan Narison

In this talk, I review the determinations of the QCD condensates and $I^\pm_{s}$ within the SVZ expansion using the ratio of Laplace sum rule (LSR) and $I ¨ $ -like moments in $e^+e^-\to I…

$2^{++}$ 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…
