Abstract
We examine the electronic width ratios of Ï resonances below the BB¯ threshold by means of an effective (Cornell-type) QCD potential incorporating 1/mb corrections obtained from a prior fit to the bottomonium spectrum. From our analysis we conclude that the Ï(2S) and Ï(3S) states should belong to the strong-coupling (nonperturbative) regime while the Ï(1S) state should belong to the weak-coupling (perturbative) regime, in agreement with a previous study based on radiative decays.
