Lambda-bar from QCD sum rules for heavy quarkonium

High Energy Physics - Phenomenology 2008-02-03 v2

Abstract

Using a specific scheme of the QCD sum rules for heavy quarkonium in the leading approximation over the inverse heavy quark mass, one gets the estimate of the difference between the masses of the heavy meson and heavy quark Λˉ=0.59±0.02\bar \Lambda = 0.59\pm 0.02 GeV.
