Evidence of a broad structure at an invariant mass of 4.32 GeV/c(2) in the reaction e(+)e(-)->pi(+)pi(-)psi(2S) measured at BABAR

Evidence of a broad structure at an invariant mass of 4.32 GeV/c(2) in the reaction e(+)e(-)->pi(+)pi(-)psi(2S) measured at BABAR

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 stru...
