Precision measurements of electroweak observables provide stringent tests of the Standard Model structure and an accurate determination of its parameters. A brief overview of the present experimental status is presented. A more extensive discussion can be found in Ref. 1.

An interesting class of models of dynamical electroweak symmetry breaking allows only the third generation fermions to acquire dynamical masses, such that the masses of the first two generations should be given by coupling to a nonstandard “Higgs” doublet. The scalars in this case have large couplings to the second generation, so that they are copiously produced at a muon collider. We analyze t...

Broad band spectra of total and compact–scale radio emission from blazars, used in combination with kinematic information inferred from VLBI monitoring programs, can be applied successfully to better constrain the models of compact jets. We discuss here a " hands-on " approach for tying together the kinematic and spectral properties of radio emission from blazars.
