Abstract
We analyze the properties of electroweak chiral effective Lagrangian with an extendedSU(2)Rgauge group. Right-handedSU(2)Rgauge bosons affect electroweak observables by mixing with electroweak gauge bosonsWL,μandBμ. We discuss all possible mass mixing terms and calculate the exact physical mass eigenvalues by diagonalization of mixing matrix without any approximate assumptions. The contributions to oblique radiative corrections parameters STU fromSU(2)Rfields are also presented.
