abstract

The Babar and CLEO collaborations have recently observed states decaying to D_s^+\pi^0 and D_s^{*+}\pi^0 respectively and suggest the possible explanation that they are the missing P-wave c\bar{s} states with J^P=0^+ and 1^+. In this note we compare the properties of the D_{sJ}^*(2317)^+ and D_{sJ}(2463)^+ states to those expected of the c\bar{s} D_{s0}^* and D_{s1} states. We expect the D_{s0}^* and D_{s1} with the reported masses to be extremely narrow, \Gamma \sim {\cal O}(10\hbox{keV}), with large branching ratios to D^*_s\gamma for the D_{s0}^* and to D^*_s\gamma and D_s\gamma for the D_{s1}. Crucial to this interpretation of the Babar and CLEO observations is the measurement of the radiative transitions. We note that it may be possible to observe the $D_{s1}(2536)$ in radiative transitions to the $D_s^*$.

  1. The $B^{+(0)} \to \bar D^{0(-)} D^{*}_{s0}(2317)^+$ decays and the molecular structure of $D^*_{s0}(2317)$

    hep-ph 2025-12 conditional novelty 6.0 of 10

    Using B→D D K data and a two-parameter model, the authors derive B→D D*_s0(2317) branching fractions that agree with experiment within errors, supporting a sizable DK molecular component of D*_s0(2317).

  2. Determination of the binding and $DK$ probability of the $D^{*}_{s0}(2317)$ from the $(\bar{D}\bar K)^-$ mass distributions in $\Lambda_{b}\to \Lambda_{c} (\bar{D}\bar K)^-$ decays

    hep-ph 2024-11 conditional novelty 6.0 of 10

    A simulation-based feasibility study shows that near-threshold Dbar Kbar mass distributions from Lambda_b decays could determine the D*_s0(2317) mass to about 4 MeV and its DK molecular probability to about 11%.

  3. Final state interaction in the $\Lambda_b\to D^+D^- \Lambda,~D^0D_s^- p,~D_s^+D_s^-\Lambda$ reactions

    hep-ph 2025-07 conditional novelty 5.0 of 10

    Threshold enhancements in the Ds-p, Ds-Lambda, and related mass distributions of Lambda_b decays are predicted from final state interactions with molecular exotic states.

  4. Investigating triply heavy tetraquark states through QCD sum rules

    hep-ph 2024-12 conditional novelty 5.0 of 10

    QCD sum rules with condensates up to dimension 9 predict triply heavy tetraquark masses of 5.4 to 6.2 GeV for charm systems and 14.9 to 15.7 GeV for bottom systems.
