Recently Babar Collaboration reported a new $c\bar{s}$ state $D_{sJ}(2860)$ and Belle Collaboration observed $D_{sJ}(2715)$. We investigate the strong decays of the excited $c\bar{s}$ states using the $^{3}P_{0}$ model. After comparing the theoretical decay widths and decay patterns with the available experimental data, we tend to conclude: (1) $D_{sJ}(2715)$ is probably the $1^{-}(1^{3}D_{1})$ $c\bar{s}$ state although the $1^{-}(2^{3}S_{1})$ assignment is not completely excluded; (2) $D_{sJ}(2860)$ seems unlikely to be the $1^{-}(2^{3}S_{1})$ and $1^{-}(1^{3}D_{1})$ candidate; (3) $D_{sJ}(2860)$ as either a $0^{+}(2^{3}P_{0})$ or $3^{-}(1^{3}D_{3})$ $c\bar{s}$ state is consistent with the experimental data; (4) experimental search of $D_{sJ}(2860)$ in the channels $D_s\eta$, $DK^{*}$, $D^{*}K$ and $D_{s}^{*}\eta$ will be crucial to distinguish the above two possibilities.

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

    hep-ph 2026-05 unverdicted novelty 5.0

    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/2...

  2. Comparing relativistic and non-relativistic quark pair creation models

    hep-ph 2026-04 unverdicted novelty 4.0

    Relativistic and non-relativistic QPC models produce strong decay width predictions of similar overall quality for light mesons, with the relativistic version exhibiting stronger suppression at high energies.
