A search for charmonium and other new states is performed in a study of exclusive initial-state-radiation production of D Dbar events from electron-positron annihilations at a center-of-mass energy of 10.58 GeV. The data sample corresponds to an integrated luminosity of 384 fb-1 and was recorded by the BABAR experiment at the PEP-II storage ring. The D Dbar mass spectrum shows clear evidence of the psi(3770) plus other structures near 3.9, 4.1, and 4.4 GeV/c^2. No evidence for Y(4260) -> D Dbar is observed, leading to an upper limit of B(Y(4260) -> D Dbar)/B(Y(4260) -> J/psi pi+ pi-) < 1.0 at 90 % confidence level.

  1. Emergence of charm-strange dibaryons with negative parity via baryon-baryon interactions

    hep-ph 2025-07 conditional novelty 6.0 of 10

    Using a one-boson-exchange model, the authors predict negative-parity charm-strange dibaryon molecules and resonances in ΞcN, ΣcΣ and related coupled channels.

  2. Constraining the $DDD^*$ three-body bound state via the $Z_c(3900)$ pole

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A model-dependent study showing that the existence of a DDD* bound state is tied to the virtual-state pole position of Zc(3900), with binding occurring only for near-threshold Zc poles.
