 +      <hidden TTP09-41  Matching QCD and HQET heavy--light currents at three loops > We consider the currents formed by a heavy and a light quark within 
 + Quantum Chromodynamics and compute the matching to Heavy Quark 
 + Effective 
 + Theory to three-loop accuracy. As an application we obtain the 
 + third-order perturbative corrections to ratios 
 + of $B$-meson decay constants.
