Description

Using the ARGUS detector operating at the DORIS II storage ring (DESY, Hamburg) the hadronic cross-section in e+e- annihilations at a center-of-mass energy of 9.36 GeV has been measured. The ratio R of the hadronic cross-section σ0(e+e-→hadrons) to the muonic cross-section σ0QED(e+e-→μ+μ-) has the value of R=3.46±0.03±0.10. (orig.)

Abstract (German)

Mit dem ARGUS-Detektor am Speicherring DORIS II (DESY, Hamburg) wurde der hadronische Wirkungsquerschnitt in e+e--Annihilationen bei einer Schwerpunktsenergie von 9.36 GeV gemessen. Das Verhaeltnis R des hadronischen Wirkungsquerschnittes σ0(e+e-→Hadronen) zu dem myonischen Wirkungsquerschnitt σ0QED(e+e-→μ+μ-) ergibt sich zu R=3.46±0.03±0.10. (orig.)
