Description
The Standard Model of the Electroweak Interactions describes the interactions of quarks and leptons through the known vector bosons, i.e. the photon and the three massive W+- and Z bosons. The first seminar will focus on the experimental aspects of the physics of the W boson at the L3 experiment at LEP, in particular with respect to the issue of the measurement of gauge couplings and radiative W-pair production. The second seminar will describe Z, and double Z production at the higher centre-of-mass energies in particular when associated to photon emission. In addition to the trilinear couplings, such events allow for the study of new quartic gauge boson vertices WWgg, WWZg and ZZgg arising from the non-Abelian gauge structure of the Standard Model. The most updated L3 results will be reported in the two seminars.
