Determination of α(M z ) from an hyperasymptotic approximation to the energy of a static quark-antiquark pair

Abstract We give the hyperasymptotic expansion of the energy of a static quark-antiquark pair with a precision that includes the effects of the subleading renormalon. The terminants associated to the first and second renormalon are incorporated in the analysis when necessary. In particular, we deter...
