The Strong g_B(**)BPi Coupling Constant in full QCD
Abstract
Description
To leading order in alpha_s, the leading and non-leading 1/m_b corrections to the excited g_B^(**) meson coupling g_B^(**)BPi is calculated in the framework of QCD spectral moment sum rules in the full theory. Our prediction is in good agreement=20 with the light-cone QCD sum rule result.
