Abstract

We analyze the properties of electroweak chiral effective Lagrangian with an extended gauge group. Right-handed gauge bosons affect electroweak observables by mixing withelectroweak gauge bosons and . We discuss all possible mass mixing terms and calculatethe exact physical mass eigenvalues by diagonalization of mixing matrix without any approximateassumptions. The contributions to oblique radiative corrections parameters STU from fields are also presented.
