dc.description.abstract | We present two determinations of the strong coupling α s . The first one is from the static energy at three-loop accuracy, and may be considered an update of earlier determinations by some of us. The new analysis includes new lattice data at smaller lattice spacings, and reaches distances as short as 0.0237 fm. We present a comprehensive and detailed estimate of the error sources that contribute to the uncertainty of the final result, α s ( M Z ) = 0.1166 0 + 0.00110 − 0.00056 . The second determination is based on lattice data for the singlet free energy at finite temperature up to distances as small as 0.0081 fm, from which we obtain α s ( M Z ) = 0.1163 8 + 0.0009 5 − 0.00087 . | - |
