| |
| |
| <hidden TTP97-33 Non-Abelian Dipole Radiation and the Heavy Quark Expansion > Dipole radiation in QCD is derived to the second order in |
| $\alpha_s$. A power-like evolution of the spin-singlet heavy quark |
| operators is obtained to the same accuracy. We give an ${\cal |
| O}(\alpha_s^2)$ relation between the short-distance low-scale running |
| heavy quark mass and the $\overline{\rm MS}$ mass. We discuss the |
| properties of an effective QCD coupling $\alpha_s^{(d)}(E)$ which |
| governs the dipole radiation. We argue that this coupling is |
| advantageous for describing heavy quark physics. |
