High Energy Physics - Phenomenology 2009-01-06 v1

Abstract

The complete list of electroweak chiral Lagrangian for W', Z' and a neutral light higgs with symmetry SU(2)1SU(2)2U(1)SU(2)_1\otimes SU(2)_2\otimes U(1) is provided. The bosonic part is accurate up to order of p4p^4, the matter part involving various fermions representation arrangements includes dimension three Yukawa type and dimension four gauge type operators. The universal mixings and masses of gauge boson and fermion are given. Constraints from mass differences for K0Kˉ0K^0-\bar{K}^0, Bd0Bˉd0B_d^0-\bar{B}_{d}^0, Bs0Bˉs0B_s^0-\bar{B}_{s}^0 systems and indirect CP violation parameter ϵK|\epsilon_K| for KK mesons are evaluated.
