Abstract
We investigate the structure of the leading IR renormalon singularity in the QCD/HQET matching coefficients for heavy–light quark currents beyond the large-β0 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 fB∗/fB.
