Measurement of the Total Hadronic Cross Section in e+e- Annihilations below 10.56 GeV
arXiv:0706.2813 · doi:10.1103/PhysRevD.76.072008
Abstract
Using the CLEO III detector, we measure absolute cross sections for e+e- --> hadrons at seven center-of-mass energies between 6.964 and 10.538 GeV. The values of R, the ratio of hadronic and muon pair production cross sections, are determined within 2% total r.m.s. uncertainty.
