Precision experimental studies of the electroweak processes are of utmost importance for understanding the mechanism of spontaneous symmetry breaking in the Standard Model (SM) and verifying the SM gauge structure predicted by the SU(2)xSU(2)xU(1) symmetry group. Furthermore, these measurements provide an insight and indirect constraints on the properties of physics beyond our current direct reach. A perfect example is constraints arising from the W mass measurement on the Higgs sector. There is a potential for discovery of new physics should a signicant deviation in the measured quantities from the SM predictions be detected. Finally, precision measurements combined with other experimental data constrain parton distribution functions (PDFs), which is important in view of upcoming LHC experiments. CDF has a strong program of electroweak measurements, some of the highlights and their motivations are: Measurement of the W mass: strong implications on the Higgs mass; Studies of the diboson production: a direct measurement of the trilinear couplings and sensitivity to new physics; Measurements of W and Z production cross-sections: a test of the higher order calcuations in the context of the SM; Studies of the W and Z production asymmetries: PDF constaints.
