Evidence of a broad structure at an invariant mass of 4.32GeV/c2 in the reaction e+e-→π+π-ψ(2S) measured at BABAR

Physical Review Letters, Volume 98, No. 21, Article 212001, Year 2007

We present a measurement of the cross section of the process e+e-→π+π-ψ(2S) from threshold up to 8 GeV center-of-mass energy using events containing initial-state radiation, produced at the SLAC PEP-II e+e- storage rings. The study is based on 298fb-1 of data recorded with the BABAR detector. A structure is observed in the cross section not far above threshold, near 4.32 GeV. We also investigate the compatibility of this structure with the Y(4260) previously reported by this experiment. © 2007 The American Physical Society.
