The effect of $B\pi$ continuum in the QCD sum rules for the $(0^{+},1^{+})$ heavy meson doublet in HQET

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 ${\bar{\Lambda }}_{+,\frac{1}{2}}$ and pionic coupling constant $g^{\prime }$.
