The ratio $$\mathcal {R}(D)$$ R(D) and the D-meson distribution amplitude
Abstract In this paper, we calculate the $$B\rightarrow D$$ B→D transition form factors (TFFs) within the light-cone sum rules (LCSRs) and predict the ratio $$\mathcal {R}(D)$$ R(D) . More accurate D-meson distribution amplitudes (DAs) are essential to get a more accurate theoretical prediction. We...
