Search for structure in σ(e+e-→hadrons) between s=10.34and11.6 GeV
The CUSB detector at the Cornell Electron Storage Ring has been used to measure R=σ(e+e-→hadrons)σ(e+e-→μ+μ-) in the c.m. energy regions between the ′′ and the ′′′, and above the ′′′ 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. © 1982 The American Physical Society.
