Abstract

It is shown that BR(χ_b1(1P)→ Z→ e⁺e^-)≃ 3.3⋅ 10^-7, BR(χ_b1(2P)→ Z→ e⁺e^-)≃ 4.1⋅ 10^-7 and BR(χ_c1(1P)→ Z→ e⁺e^-)≃ 10^-8 that give a good chance to search for the direct production of pseudovector ³P₁ heavy quarkonia in e⁺e^- collisions (e⁺e^-→ Z→ ³P₁) even at current facilities not to mention b and c-τ factories. Leading radiative corrections to annihilation of quarkonia in QCD are discussed.
