Non-factorisable effects in the decays B ¯ s 0 → D s + π − $$ {\overline{B}}_s^0\to {D}_s^{+}{\pi}^{-} $$ and B ¯ 0 → D + K − $$ {\overline{B}}^0\to {D}^{+}{K}^{-} $$ from LCSR

Abstract In light of the current discrepancies between the recent predictions based on QCD factorisation (QCDF) and the experimental data for several non-leptonic colour-allowed two-body B-meson decays, we obtain new determinations of the non-factorisable soft-gluon contribution to the decays B ¯ s...
