Abstract :
A systematic theoretical evaluation of the cross section for hadron production in electron-positron collisions in the energy range just below the B meson threshold is presented which includes charm and bottom mass effects and is accurate to order αs3. The corresponding measurement in the energy region several GeV above the threshold is also discussed.
