====== TTP94-31 HQQET: An Effective Theory Approach to Heavy Quarkonia Decays ======
 
 
<hidden TTP94-31  HQQET: An Effective Theory Approach to Heavy Quarkonia Decays > We discuss systems containing a heavy quark and a heavy antiquark in
 the infinite mass limit of QCD.  Studying the limit of equal
 velocities for both heavy particles, we formulate an effective theory
 approach to heavy quarkonia-like systems.  The method is well suited
 to processes in which the two heavy quarks annihilate, such as
 electromagnetic and strong decays of charmonium and bottomonium and
 weak decays of $B_c$.
