摘要：
The complete list of electroweak chiral Lagrangian for W', Z' and a neutral light higgs with symmetry SU(2)(1) circle times SU(2)(2) circle times U(1) is provided. The bosonic part is accurate up to order of p(4), the matter part involving various fermion representation arrangements includes dimension three Yukawa type and dimension four gauge type operators. The universal mixings and masses of gauge bosons and fermions are given. Constraints from mass differences for K-0-(K) over bar (0), B-d(0)- (B) over bar (0)(d), B-s(0)-(B) over bar (0)(s) systems and indirect CP violation parameter vertical bar epsilon(K)vertical bar for K mesons are evaluated.
