Measurements of the cross sections for open charm and beauty production in γγ collisions at s=189–202 GeV
Abstract
The production of c and b quarks γγ collisions is studied with the L3 detector at LEP with 410 pb−1 of data, collected at centre-of-mass energies from 189 GeV to 202 GeV. Hadronic final states containing c and b quarks are identified by detecting electrons or muons from their semileptonic decays. The cross sections σ(e+e−→e+e−cc̄X) and σ(e+e−→e+e−bb̄X) are measured and compared to next-to-leading order perturbative QCD calculations. The cross …
