 +====== TTP06-25 Decoupling of heavy quarks in HQET ====== 
 +  
 +  
 +      <hidden TTP06-25 ​ Decoupling of heavy quarks in HQET > Decoupling of c-quark loops in b-quark HQET is considered. 
 + The decoupling coefficients for the HQET heavy-quark field 
 + and the heavy-light quark current are calculated with the three-loop accuracy. 
 + The last result can be used to improve the accuracy 
 + of extracting f_B from HQET lattice simulations 
 + ​(without c-quark loops). 
 + The decoupling coefficient for the flavour-nonsinglet QCD current 
 + with n antisymmetrized \gamma-matrices is also obtained at three loops; 
 + the result for the tensor current (n=2) is new.
