Unquenched quark model calculations show coupled-channel effects lower masses of higher D and Ds excitations; D_s1(2933) is assigned as mixed D_s(2P1), D_sJ(3040) favors D_s(3^1S0), while D(3000) fits none of the 3S/2P/2D/1F states.

A coupled-channel model of meson-meson interactions reproduces the LHCb D*π mass distribution in B decays and yields a D*π scattering length.
Covariant light-front calculations predict branching ratios of 10^{-5} to 10^{-3} for B(s) to D(s)(2S) and D*(s)(2S) plus light mesons, larger than Bethe-Salpeter results but consistent with other quark models.
The unmeasured fraction of inclusive semileptonic B to charm decays is dominated by final states without D mesons, likely from baryons and Ds mesons.

Higher excited charmed and charmed-strange mesons in an unquenched quark model

$D_{(s)}(2S)$ and $D^{*}_{(s)}(2S)$ production in nonleptonic $B_{(s)}$ weak decays
Covariant light-front calculations predict branching ratios of 10^{-5} to 10^{-3} for B(s) to D(s)(2S) and D*(s)(2S) plus light mesons, larger than Bethe-Salpeter results but consistent with other quark models.

Closing the knowledge gap in semileptonic $B\rightarrow X_c\ell\nu$ decays
The unmeasured fraction of inclusive semileptonic B to charm decays is dominated by final states without D mesons, likely from baryons and Ds mesons.
