(ProQuest: ... denotes formulae and/or non-USASCII text omitted) We report new measurements of the total cross sections for e super(+)e super(-) arrow right Upsilon(n S)pi super(+)pi super(-)(n=1, 2, 3) and e super(+)e super(-) arrow right bb from a high-luminosity fine scan of the region sradical=10.63-11.05GeV with the Belle detector. We observe that the Upsilon(nS)pi super(+)pi super(-) spectra have little or no nonresonant component and extract from them the masses and widths of Upsilon(10860) and Upsilon(11020) and their relative phase. We find ...MeV/c super(2) and ...MeV and report first measurements ...MeV/c super(2), ...MeV, and ...rad.
