We report the first observation of the B --> Dbar DsJ(2317) and B --> Dbar DsJ(2457) decays based on 123.8 10^6 BBar events collected with the Belle detector at KEKB. We observe the DsJ(2317) decay to Ds pi0 and DsJ(2457) decay to the Ds* pi0 and Ds gamma final states. We also set 90% CL upper limits for the decays DsJ(2317) --> Ds* gamma, DsJ(2457) --> Ds* gamma, DsJ(2457) --> Ds pi0 and DsJ(2457) --> Ds pi+ pi-.

  1. Observation of a new excited charm-strange meson $D_{s1}(2933)^+$ in $B^0\to D^+ D^- K^+ \pi^-$ decays

    hep-ex 2026-04 accept novelty 8.0

    A new charm-strange resonance D_s1(2933)^+ with J^P=1^+ is observed at >10 sigma in B^0 to D+ D- K+ pi- decays, with measured mass 2933 MeV and width 72 MeV.

  2. Compact $cs\bar{s}\bar{s}$ Tetraquarks in the Charm--Strange Sector: Mass Spectra, Rearrangement Decays and Regge Trajectories with $D_s$ Threshold Inputs

    hep-ph 2026-05 unverdicted novelty 5.0

    The authors compute mass spectra, rearrangement decays, and Regge trajectories for cs s-bar s-bar tetraquarks modeled as axial [cs][s-bar s-bar] systems in a Cornell potential framework with Ds threshold inputs.

  3. Coupled-channel study of the three-body $DDK$ and $D^{*}D^{*}K$

    hep-ph 2026-04 unverdicted novelty 5.0

    The DDK system supports a deeply bound compact state across wide parameters and possibly a shallow three-body halo state near the D-DK threshold, with negligible D*D*K coupling and no resonances.

  4. What can we learn from the radiative decays of the $D_{s1}(2460)$ meson?

    hep-ph 2025-12 unverdicted novelty 5.0

    Measuring the ratio of radiative decay branching fractions from Ds1(2460) can probe the nature of Ds0*(2317) and Ds1(2460) mesons.
