On the Casimir scaling violation in the cusp anomalous dimension at small angle

Andrey Grozin, Johannes Henn, Maximilian Stahlhofen

We compute the four-loop $n_{f}$ contribution proportional to the quartic Casimir of the QCD cusp anomalous dimension as an expansion for small cusp angle $ϕ$ . This piece is gauge in…

Towards a Next-to-Next-to-Leading Order analysis of matching in $B^{0}$ - $B ˉ^{0}$ mixing

Andrey G. Grozin, Thomas Mannel, Alexei A. Pivovarov

We compute perturbative corrections to matching coefficients of QCD to HQET for the matrix element of the $Δ B = 2$ operator that determines the mass difference in $B^{0} - B ˉ^{0}$ sys…

Heavy quark form factors in the large $β_{0}$ limit

A. G. Grozin

Heavy quark form factors are calculated at $β_{0} α_{s} \sim 1$ to all orders in $α_{s}$ at the first order in $1/ β_{0}$ . The $n_{f}^{2} α_{s}^{3}$ terms in the recent results [arXiv:1611.07535] f…
