1. L3 experiment

    The most important results of the L3 experiment, as is known, are as follows.
Z-boson mass has been determined with high precision, the probability of the decay Z --> has been determined, and the number of generation of massless neutrino has been determined (Nv=2.978±0.014), the Standard Model (SM) predictions have been confirmed, and Weinberg angle has been estimated with high accuracy, the top-quark mass has been predicted in the frame of SM from higher order weak radiative corrections. Significant efforts of the L3 activity were focused on the search for Higgs bosons and precise measurements of the properties of the W boson. Detailed studies of resonance formation in two-photon interactions were performed. By present, the L3 experiment has been completed.
