摘要:

A sample of ∼ 91 fb−1ofe+e−interactions at center of mass energy near 10.6 GeV/cfrom the PEP‐II asymmetric collider at SLAC has been examined by theBABARcollaboration. Evidence for a narrow state with mass 2317 MeV/c2decaying toDs+&pgr;0is found. These data, showing the signal and properties of the state, are presented. Evidence for a second state at ∼2460 MeV/c2decaying toDss&pgr;0is also shown. Data from other experiments are shown, and possible implications of the existence of these states discussed. © 2003 American Institute of Physics
