Observation of a narrow meson state decaying to Ds + π0 at a mass of 2.32 GeV/c2
In 91 fb-1 of data collected by the BABAR experiment, a narrow state in the inclusive Ds +π mass distribution near 2.32 GeV/c2 was observed. No evidence was found for the decay of this state to Ds +γ, Ds *(2112)+γ, or Ds +γγ.
