$D\rightarrow \pi$ transitions from QCD Light-Cone Sum Rules with the chiral currents

We present a systematic study of the transition form factors for the semileptonic decays $D\rightarrow Pe^{+}v_{e}$ and $D\rightarrow P\mu^{+}\bar{v}_{\mu}$ using QCD light-cone sum rules with chiral currents, with emphasis on the nonperturbative structure of the pion. The distribution amplitudes of the meson $\pi$, in...
