2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/37399The measurements of four-fermion production rates performed at LEP2 in e+e- collisions at centre-of-mass energies ranging from 161 to 209 GeV are presented. The focus is put on processes that involve the production and decay of W or Z electroweak bosons. Results on W decay rates and couplings are also discussed.5 pages, 3 figures.
