Bounds on hadronic contributions to the anomalous magnetic moment of the 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 lepton ($a_τ…
Bottom-Charm Diquark Masses from QCD Laplace Sum-Rules
T. de Oliveira, D. Harnett, J. Ho +5
Constituent mass predictions for bottom-charm color-antitriplet diquarks are generated using QCD Laplace sum rules. We calculate the diquark correlator within the operator p…
Lepton 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, , as a natural low-energy window quantity that ma…
An Application of Diagrammatic Renormalization to Tensor Di-Gluonium
T. de Oliveira, Siyuan Li, T. G. Steele
We apply the diagrammatic renormalization method to the NLO analysis of the tensor di-gluonium channel within the QCD sum-rules approach. Diagrammatic renormalization elim…
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 tensor di-gluonium by using relativistic QCD Laplace sum rules (LSR). In so doing, we evaluate the next-to-lea…
Bounds on using Hölder's inequalities and finite-energy QCD sum rules
Siyuan Li, T. G. Steele, J. Ho +3
This study establishes bounds on the leading-order (LO) hadronic vacuum polarization (HVP) contribution to the anomalous magnetic moment of the muon (, $a_μ=…
QCD bounds on leading-order hadronic vacuum polarization contributions to the muon anomalous magnetic moment
Siyuan Li, T. G. Steele, J. Ho +3
QCD bounds on the leading-order (LO) hadronic vacuum polarization (HVP) contribution to the anomalous magnetic moment of the muon (, $a_μ=\left(g-2\right)_μ/…
Numerically Computing Finite Temperature Loop Integrals using pySecDec
D. Harnett, Siyuan Li, T. G. Steele
Finite-temperature quantum field theory provides the foundation for many important phenomena in the Standard Model and extensions, including phase transitions, baryogenesis, and gr…
Tensor Di-Gluonium from Laplace Sum Rules at NLO
S. Li, S. Narison, T. Steele +1
We evaluate the next-to-leading (NLO) corrections to the perturbative (PT) and condensate and the LO constant term of the contributions to the tens…
