Query: Beauty Vector Meson Decay Constants from QCD Sum Rules   We present the outcomes of a very recent investigation of the decay constants
of nonstrange and strange heavy-light beauty vector mesons, with special
emphasis on the ratio of any such decay constant to the decay constant of the
corresponding pseudoscalar meson, by means of Borel-transformed QCD sum rules.
Our results suggest that both these ratios are below unity.
