Theoretical estimate of the D^* to Dπ decay rate
read the original abstract
We present the results of our lattice QCD study of the $g_{D^* D\pi}i$ coupling, relevant to the $D^\ast \to D\pi$ decay. Our computation is made on the gauge field configurations that include $N_f=2$ dynamical light quarks by using the twisted mass QCD action. From the results obtained at four different lattice spacings we were able to take for the first time the continuum limit of this quantity computed on the lattice. Our final value, $g_c=0.53(3)(3)$, leads to $\Gamma(D^{\ast +}\to \bar{D}^0 \pi^+)= (50\pm 5\pm 6)$ keV, and is in good agreement with the experimental results for the width of the charged $D^\ast$-meson.

Analysis of the $D_0^*(2300)$ resonance from lattice QCD under chiral symmetry
Chiral symmetry corrections in lattice QCD fits shift the D0*(2300) resonance pole closer to the Dπ threshold and reduce its width, while coupled channels produce a two-pole structure.

Heavy meson chiral perturbation theory constraints on a charm-coupled GeV-scale QCD axion
A charm-only QCD axion model passes a heavy-meson EFT consistency check, with its tightest bound coming from σ-mediated B_s mixing.
