Measurement of W Boson Properties with the L3 experiment at LEP
Artur Barczyk


Abstract


Since the LEP energy passed the WW production threshold in 1996, a large amount of data has been collected, enabling precise determination of a wide range of W boson parameters. These measurements are a fundamental test of the Standard Model, and pose constraints on predictions in its undisclosed parts. In this talk, I'll review the results obtained by the L3 experiment on the measurement of the WW cross section at centre-of-mass energies between 161 and 202 GeV. The branching ratios of the W boson will also be presented, as well as the measurement of the W mass and the triple gauge boson couplings (TGCs).
