 +====== TTP02-11 Asymptotics of the Perturbative Series for $f_{B^*} /f_B$ ======

 +  
 +   <​hidden TTP02-11 ​ Asymptotics of the Perturbative Series for $f_{B^*} /f_B$ > We investigate the structure of the leading IR renormalon singularity 
 + in the QCD/HQET matching coefficients for heavy-light quark currents 
 + ​beyond the large-\beta_0 limit. 
 + From this result, we derive the large-order behaviour 
 + of the perturbative series for these coefficients,​ 
 + and for ratios of meson matrix elements, such as f_{B^*}/​f_B.
