Determination of $∣ V_{c b} ∣$ using N $^{3}$ LO perturbative corrections to $Γ (B \to X_{c} ℓ ν)$ and 1S masses

Yuuki Hayashi, Yukinari Sumino, Hiromasa Takaura

We determine $∣ V_{c b} ∣$ using the third-order perturbative series for the inclusive semileptonic $B$ decay width and for the masses of the bottomonium 1S states. We use the masses…

New method for renormalon subtraction using Fourier transform

Yuuki Hayashi, Yukinari Sumino, Hiromasa Takaura

To improve accuracy in calculating QCD effects, we propose a method for renormalon subtraction in the context of the operator-product expansion. The method enables subtracting reno…

UV contributions to energy of a static quark-antiquark pair in large $β_{0}$ approximation

Yuuki Hayashi, Yukinari Sumino

The total energy of a static quark-antiquark pair $E_{tot} (r) = 2 m_{pole} + V_{QCD} (r)$ is known to be predictable up to $O (Λ_{QCD}^{3} r^{2})$ and ${\cal O}(\frac{Λ…
