OPE Analysis of QCD Potential and Determination of ΛMS Presenter: Yukinari Sumino Y. Sumino Abstract: We analyze the static QCD potential VQCD (r) in the distance region 0.1 fm < r < 1 fm. In the frame of operator-product expansion (OPE), we compare numerically perturbative predictions of the leading Wilson coefficient and lattice computations of VQCD (r), assembling recent developments of the computations. A very good agreement is observed. We perform fits to simultaneously determine non-perturbative contribution to VQCD (r) and the relation between Sommer scale and Λ3-loop . As for the former quantity, we MS improve bounds as compared to the previous determination; as for the latter quantity, our analysis provides a new method for its determination, where we 3-loop = 0.574 ± 0.042. find r0 ΛMS 1
