Measurement of hadron and lepton-pair production from e+e- annihilation at centre-of-mass energies of 130 and 136 GeV

Hadronic and leptonic cross-sections and forward-backward asymmetries are measured using 5.7~pb$^{-1}$ of data taken with the ALEPH detector at LEP at $\cms$ energies of 130 and 136~GeV. The results agree with Standard Model expectations. The measurement of hadronic cross-sections far away from the...

Sumario:Hadronic and leptonic cross-sections and forward-backward asymmetries are measured using 5.7~pb$^{-1}$ of data taken with the ALEPH detector at LEP at $\cms$ energies of 130 and 136~GeV. The results agree with Standard Model expectations. The measurement of hadronic cross-sections far away from the Z resonance improves the determination of the interference between photon and Z exchange. Constraints on models with extra Z bosons are presented.
