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 centre-of-mass 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.

Abstract
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 centre-of-mass 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.File in questo prodotto:
