Title: Measurements of the Υ ( 10860 ) and Υ ( 11020 ) resonances via σ ( e + e - Υ ( n S ) π + π - )

Abstract

We report new measurements of the total cross sections for e + e - Υ ( n S ) π + π - ( n = 1 , 2, 3) and e + e - b b ¯ from a high-luminosity fine scan of the region s = 10.63 11.05 GeV with the Belle detector. We observe that the Υ ( n S ) π + π - spectra have little or no nonresonant component and extract from them the masses and widths of Υ ( 10860 ) and Υ ( 11020 ) and their relative phase. We find M 10860 = ( 10891.1 ± 3. 2 - 1.7 + 0.6 ) MeV / c 2 and Γ 10860 = ( 53. 7 - 5.6 - 5.4 + 7.1 + 1.3 ) MeV and report first measurements M 11020 = ( 10987. 5 - 2.5 - 2.1 + 6.4 + 9.0 ) MeV / c 2 , Γ 11020 = ( 6 1 - 19 - 20 + 9 + 2 ) MeV , and Φ 11020 - Φ 10860 = ( - 1.0 ± 0.4 - 0.1 + 1.4 ) rad
