Abstract

In this paper, we perform a combined study of $2 S$ and $1 D$ open-charm mesons with natural spin-parity. Our results indicate that $D_{1}^{*} (2600) / D_{s 1}^{*} (2700)$ and $D_{1}^{*} (2760) / D_{s 1}^{*} (2860)$ are predominantly the $2 {}^{3}{S_{1}}$ and $1 {}^{3}{D_{1}}$ charmed/charmed-strange mesons, respectively, while $D_{3}^{*} (2760) / D_{s 3}^{*} (2860)$ can be regarded as the $1 {}^{3}{D_{3}}$ charmed/charmed-strange mesons. In addition, some typical ratios of partial widths of the discussed natural states are predicted, by which future experiments can test these assignments, especially for the $2 S − 1 D$ mixing scheme existing in $D_{1}^{*} (2600) / D_{1}^{*} (2760)$ and $D_{s 1}^{*} (2700) / D_{s 1}^{*} (2860)$ .
