the ${{\mathit D}^{+}}{{\mathit \pi}^{-}}$ wave together with virtual contributions from the ${{\mathit D}^{*}{(2007)}^{0}}$ and ${{\mathit B}^{*0}}$ states, and components corresponding to the ${{\mathit D}_{{{2}}}^{*}{(2460)}^{0}}$, ${{\mathit D}_{{{1}}}^{*}{(2680)}^{0}}$, ${{\mathit D}_{{{3}}}^{*}{(2760)}^{0}}$, and ${{\mathit D}_{{{2}}}^{*}{(3000)}^{0}}$ resonances. 2  From the amplitude analysis in the model describing the ${{\mathit D}^{+}}{{\mathit \pi}^{-}}$ wave together with virtual contributions from the ${{\mathit D}^{*}{(2007)}^{0}}$ and ${{\mathit B}^{*0}}$ states, nonresonant spin-0 and spin-1 components as well as the ${{\mathit D}_{{{0}}}^{*}{(2400)}^{0}}$, ${{\mathit D}_{{{2}}}^{*}{(2460)}^{0}}$ and ${{\mathit D}_{{{1}}}^{*}{(2760)}^{0}}$ resonances. 3  From the Dalitz plot analysis including various ${{\mathit K}^{*}}$ and ${{\mathit D}^{**}}$ mesons as well as broad structures in the ${{\mathit K}}{{\mathit \pi}}{\mathit S}{\mathrm -wave}$ and the ${{\mathit D}}{{\mathit \pi}}$ $\mathit S$- and ${\mathit P}{\mathrm -wave}$s. 4  Modeling the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{\mathit S}{\mathrm -wave}$ with the Isobar formalism. 5  From the combined fit of the ${{\mathit M}}({{\mathit D}^{+}}{{\mathit \pi}^{-}}$) and ${{\mathit M}}({{\mathit D}^{*+}}{{\mathit \pi}^{-}}$) distributions. and A$_{{{\mathit D}_{{{2}}}}}$ fixed to the theoretical prediction of $-1$. 6  From the fit of the ${{\mathit M}}({{\mathit D}^{0}}{{\mathit \pi}^{+}}$) distribution. The widths of the ${{\mathit D}_{{{1}}}^{+}}$ and ${{\mathit D}_{{{2}}}^{*+}}$ are fixed to 25 MeV and 37 MeV, and A$_{{{\mathit D}_{{{1}}}}}$ and A$_{{{\mathit D}_{{{2}}}}}$ are fixed to the theoretical predictions of 3 and $-1$, respectively. 7  At a fixed width of 50.5 MeV. 8  Fit includes the contribution from ${{\mathit D}_{{{0}}}^{*}{(2400)}^{0}}$. 9  Modeling the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{\mathit S}{\mathrm -wave}$ with the K-matrix formalism. 10  Calculated using the mass difference $\mathit m({{\mathit D}_{{{2}}}^{*0}}$) $−$ $\mathit m({{\mathit D}^{*+}})_{PDG}$ reported below and $\mathit m({{\mathit D}^{*+}})_{PDG}$ = $2010.27$ $\pm0.17$ MeV. The 0.17 MeV uncertainty of the PDG mass value should be added to the experimental uncertainty of ${}^{+1.2}_{-1.3}$ MeV. 11  Fit includes the contribution from ${{\mathit D}_{{{0}}}^{*}{(2400)}^{\pm}}$. Not independent of the corresponding mass difference measurement, (${\mathit m}_{{{\mathit D}_{{{2}}}^{*}{(2460)}^{\pm}}}$) $−$ (${\mathit m}_{{{\mathit D}_{{{2}}}^{*}{(2460)}^{0}}}$). 12  No systematic error given.
