====== TTP98-23 Perturbative QCD calculations with heavy quarks ====== We review recent calculations of second order corrections to heavy quark decays. Techniques developed in this context are applicable to many processes involving heavy charged particles, for example the nonabelian dipole radiation. Calculations involving relativistic radiating particles are also discussed. |**Andrzej Czarnecki and Kirill Melnikov** | |** Proceedings of Lake Louise Winter Institute: Quantum Chromodynamics, Lake Louise, Alberta, Canada 1998. ** | | {{preprints:1998:ttp98-23.pdf|PDF}} {{preprints:1998:ttp98-23.ps|PostScript}} [[http://arxiv.org/abs/hep-ph/9806258|arXiv]] | | |
