Lattice calculation of $1/p^2$ corrections to ${\alpha }_s$ and of ${\Lambda }_{\mathrm{QCD}}$ in the $\widetilde{MOM}$ scheme

Ph. Boucaud, G. Burgio, F. Di Renzo +8

We report on very strong evidence of the occurrence of power terms in $\as(p)$, the QCD running coupling constant in the $\widetilde{MOM}$ scheme, by analyzing non-perturbative mea…
