Determination of $B$-meson distribution amplitudes from $B\to \pi ,K,D$ transition form factors

Dong-Hao Li, Cai-Dian Lü, Ulf-G. Meißner +1

Recent work on $B\to \pi$, $K$ and $B\to D$ form factors from lattice QCD and light-cone sum rules has made it possible to constrain the inverse moment ${\lambda }_B$ of the $B$-meson light-…
