We report a study of DsJ*(2317)+ and DsJ(2460)+ meson production in B decays. We observe the decays B+ -> DsJ(*)+ Dbar(*)0 and B0 -> DsJ(*)+ D(*)- with the subsequent decays DsJ*(2317)+ -> Ds+ pi0, DsJ(2460)+ -> Ds+ gamma, and DsJ(2460)+ -> Ds*+ pi0. Based on a data sample of 122.1 million BBbar pairs collected with the BaBar detector at the PEP-II B factory, we obtain branching fractions for these modes, including the previously unseen decays B -> DsJ(*)+ D*. In addition, we perform an angular analysis of DsJ(2460)+ -> Ds+ gamma decays to test the different DsJ(2460)+ spin hypotheses.

  1. Strong decays of the possible $D^{*}K$ and $\bar{D}^{*}K$ molecules

    hep-ph 2026-08 conditional novelty 4.0 of 10

    An effective-Lagrangian calculation predicts the I=1 D*K molecule T^a_cs1(2470) has a D_s*pi0 width of 13 to 196 MeV, about 10^3 times the predicted D_s1(2460) molecular width.

  2. Unquenched Charmonium and Beyond

    hep-ph 2026-02 conditional novelty 2.0 of 10

    This Lanzhou-group review argues that coupled-channel (unquenched) effects, not exotic constituents, are the common thread explaining charmonium anomalies from the rho-pi puzzle to the Y-problem states.
