Résumé

We measure the production cross sections for e⁺e ^-→Υ(1S)π⁺π^-, Υ(2S)π⁺π^-, and Υ(3S) π⁺π^- as a function of √s between 10.83 GeV and 11.02 GeV. The data consist of 8.1fb^-1 collected with the Belle detector at the KEKB e⁺e^- collider. We observe enhanced production in all three final states that does not agree well with the conventional Υ(10860) line shape. A fit using a Breit-Wigner resonance shape yields a peak mass of [10888.4-2.6+2.7(stat)±1.2(syst)]MeV/c2 and a width of [30.7-7.0+8.3(stat)±3.1(syst)]MeV/c2.
