Uncertainties of the $$B\rightarrow D$$ B→D transition form factor from the D-meson leading-twist distribution amplitude
Abstract The $$B\rightarrow D$$ B→D transition form factor (TFF) $$f^{B\rightarrow D}_+(q^2)$$ f+B→D(q2) is determined mainly by the D-meson leading-twist distribution amplitude (DA) , $$\phi _{2;D}$$ ϕ2;D , if the proper chiral current correlation function is adopted within the light-cone QCD sum r...
