QCD sum rules with spectral densities solved in inverse problems

Hsiang-nan Li, Hiroyuki Umeeda

We construct QCD sum rules for nonperturbative studies without assuming the quark-hadron duality for the spectral density at low energy on the hadron side. Instead, both resonance…

Vacuum polarization contribution to muon $g - 2$ as an inverse problem

Hsiang-nan Li, Hiroyuki Umeeda

We analyze the electromagnetic current correlator at an arbitrary photon invariant mass $q^{2}$ by exploiting its associated dispersion relation. The dispersion relation is turned in…

$D$ meson mixing as an inverse problem

Hsiang-nan Li, Hiroyuki Umeeda, Fanrong Xu +1

We calculate the parameters $x$ and $y$ for the $D$ meson mixing in the Standard Model by considering a dispersion relation between them. The dispersion relation for a fictitious c…
