abstract

We study the effect of $B\pi$ continuum in the QCD sum rule analysis of the heavy meson doublet $(0^+, 1^+)$ in the leading order of heavy quark effective theory. New sum rules are derived for the leading order binding energy ${\bar \Lambda_{+,{1\over 2}}}$ and pionic coupling constant $g'$.
