====== TTP97-16 Heavy-quark effective field theory ====== The heavy quark expansion in QCD became a widely used tool in heavy quark physics. The theoretical aspects of the $1/m_Q$ expansion ($m_Q$ being the mass of the heavy quark) and some techniques as they appear in practical calculations are reviewed. Some applications to processes involving heavy quark decays are discussed. |**Thomas Mannel** | |** Rep. Prog.
