| Measurement of Hadron and Lepton-Pair Production From E (2007) | |||||||||||||
Abstract | |||||||||||||
| Hadronic and leptonic cross-sections and forward-backward asymmetries are measured using 5.7 pb \Gamma1 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. Submitted to Physics Letters B The ALEPH Collaboration D. Buskulic, I. De Bonis, D. Decamp, P. Ghez, C. Goy, J.-P. Lees, A. Lucotte, M.-N.
