Description

Formulas are obtained for the three-gluon annihilation rates of 3D quarkonium states. For the Υ(1D) we estimate Γ(3DJ → 3g) = (2.2, 0.26, 1.1) keV for J = (1, 2, 3). The smallness of these rates as compared with the expected electric-dipole rates, Γ(1D→1P+γ)∝10-30 keV, is favorable for observing the 1D in electromagnetic transitions of the Υ(3S). (orig.)
