Using the fixed-order perturbation theory (FOPT) prescription, we find $\alpha_s(m_\tau)=0. 3077\pm 0. 0075$, which corresponds to the five-flavor result $\alpha_s(M_Z)=0. 1171\pm 0. 0010$ at the $Z$ mass.

In this paper we consider the decay $D^+\to\pi^+\ell^+\ell^-$, addressing in particular the resonance contributions as well as the relatively large contributions from the weak annihilation diagrams.
