Description
The CUSB detector at the Cornell electron storage ring has been used to measure R-sigma(e+e-→hadrons)/sigma(e+e-→μ+μ-) in the c.m. energy regions between the UPSILON'' and the UPSILON''', and above the UPSILON''' up to √s = 11.6 GeV, with integrated luminosities of 5000 and 2100 nb-1, respectively. No narrow resonances are observed, and limits on the leptonic widths are presented. The average value of R increases by 0.31 +- 0.06 across the flavor threshold
