Renormalon Subtraction in OPE by Dual Space Approach: Nonlinear Sigma Model and QCD
Yuuki Hayashi, Go Mishima, Yukinari Sumino +1
It is becoming more important to subtract renormalons efficiently from perturbative calculations, in order to achieve high precision QCD calculations. We propose a new framework ``…
Inclusive determination in mass scheme using dual-space-renormalon-subtraction method
Yuuki Hayashi, Go Mishima, Yukinari Sumino +1
We determine from the inclusive semileptonic decay width of the meson with the known NLO perturbative coefficients for the first time in the $\overline{\mathrm{M…
Determination of using NLO perturbative corrections to and 1S masses
Yuuki Hayashi, Yukinari Sumino, Hiromasa Takaura
We determine using the third-order perturbative series for the inclusive semileptonic decay width and for the masses of the bottomonium 1S states. We use the masses…
Renormalon subtraction in OPE using Fourier transform: Formulation and application to various observables
Yuuki Hayashi, Yukinari Sumino, Hiromasa Takaura
Properly separating and subtracting renormalons in the framework of the operator product expansion (OPE) is a way to realize high precision computation of QCD effects in high energ…
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…

Yukinari Sumino, Hiromasa Takaura
We investigate the [] and [] renormalons in the static QCD potential in position space and momentum space usin…
