On order ${\Lambda }_{\mathrm{QCD}}^2/m$ renormalons in quarkonium system

Takuya Agemura, Yukinari Sumino

For the heavy quarkonium system we examine $\mathcal{O}({\Lambda }_{\mathrm{QCD}}^2/m)$ renormalons, which are expected to be included in the perturbative series of the pole mass and $1/(m{r}^2)$ int…
