====== TTP98-11 Spin Effects in Heavy Quark Processes ====== In the infinite mass limit for a heavy quark its spin decouples from the QCD dynamics, which leads to the heavy-quark spin symmetry. After a short discussion of spin symmetry some applications are considered. |**Thomas Mannel** | |** Acta Phys. Polon.
