Fermion pair production at Lep2 from 130 to 196 GeV

Description

The e+e- -> ff-bar cross sections and asymmetries are presented for data taken at centre of mass energy between 130 and 196 GeV, including the events recorded in the early summer 99 at 192 and 196 GeV by the ALEPH, DELPHI, L3 and OPAL collaborations. After a brief recall of the fermion pair production features above the Z resonance, the combined 4-Lep experiment cross-sections and asymmetries are given and their major systematics discussed, including heavy quark flavour production and the associated tagging methods. Finally the searches for the flavour changing neutral current process e+e- -> tc-bar(u-bar) are summarized. (authors)
