mΛQCD scale in heavy quarkonium

Abstract

We investigate the effects produced by the three-momentum scale √ mΛQCD in the strong coupling regime of heavy quarkonium. We compute the leading non-vanishing contributions due to this scale to the masses and inclusive decay widths. We find that they may provide leading corrections to the S-wave decay widths but only subleading corrections to the masses. Preprint submitted to Elsevier Science 1 February 2008
