Cross section of hadron production in yy collisions at LEP

The reaction e+e-→e+e-y*y*→e+e- hadrons is analysed using data collected by the L3 detector during the LEP runs at √s= 130-140 GeV and √s= 161 GeV. The cross sections σ(e+e-→e+e-hadrons) and σ(yy → hadrons) are measured in the interval 5 ≤ W<sub>yy</sub> ≤ 75 GeV. The energy dependence o...

Sumario:The reaction e+e-→e+e-y*y*→e+e- hadrons is analysed using data collected by the L3 detector during the LEP runs at √s= 130-140 GeV and √s= 161 GeV. The cross sections σ(e+e-→e+e-hadrons) and σ(yy → hadrons) are measured in the interval 5 ≤ W<sub>yy</sub> ≤ 75 GeV. The energy dependence of the σ(yy → hadrons) cross section is consistent with the universal Regge behaviour of total hadronic cross sections.
