Fermion pair production at LEP II

In 1995-2000 the LEP collider was operated at the energies significantly above the region of Z resonance. I present the results of the four LEP experiments on the measurement of the fermion pairs at the highest energy (up to 209 GeV). The experiments have studied the production of leptons, inclusive...

Sumario:In 1995-2000 the LEP collider was operated at the energies significantly above the region of Z resonance. I present the results of the four LEP experiments on the measurement of the fermion pairs at the highest energy (up to 209 GeV). The experiments have studied the production of leptons, inclusive quark pairs and pairs of tagged heavy quarks. Production cross-sections and asymmetries were measured. No sign of the "new physics" have been observed and stringent constrains were imposed on the theories beyond the Standard Model.
