Reconstruction of heavy quark current correlators at O(α_s^3)

Y. Kiyo, A. Maier, P. Maierhoefer +1

We construct approximate formulas for the O(α_s^3) QCD contributions to vector, axial-vector, scalar and pseudo-scalar quark current correlators, which are valid for arbitrary valu…

$O (α α_{s})$ corrections to the $γ t t ˉ$ vertex at the top quark threshold

Yuichiro Kiyo, Dirk Seidel, Matthias Steinhauser

We compute the last missing piece of the two-loop $O (α α_{s})$ corrections to $γ t t ˉ$ vertex at the $t t ˉ$ threshold due to the exchange of a $W$ boson and a gluon. T…

NNNLO correction to the toponium and bottomonium wave-functions at the origin

M. Beneke, Y. Kiyo, A. Penin +1

We report new results of the NNNLO correction to the S-wave quarkonium wave-functions at the origin, which also provide an estimate of the resonance cross section in t-tbar thresho…
