HEAVY-QUARK EFFECTIVE THEORY ON THE LIGHT-FRONT

The light front heavy quark effective theory is derived to all orders in 1/m(Q). In the limit m(Q)-->infinity, the theory exhibits the famil iar heavy quark spin-flavor symmetry. This new formalism permits a str aightforward canonical quantization to all orders in 1/m(Q); moreover, higher order terms have rather simple operator structures. The light front heavy quark effective theory can serve as a useful framework for the study of nonperturbative QCD dynamics of heavy hadron bound state s.
