D. Buskulic et al., MEASUREMENT OF HADRON AND LEPTON-PAIR PRODUCTION FROM E(-) ANNIHILATION AT CENTER-OF-MASS ENERGIES OF 130 AND 136 GEV()E(), Physics letters. Section B, 378(1-4), 1996, pp. 373-384
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-se
ctions far away from the Z resonance improves the determination of the
interference between photon and Z exchange. Constraints on models wit
h extra Z bosons are presented.
