A formulation of the linear $\sigma$ model with derivative interactions is studied. The classical theory is on-shell equivalent to the $\sigma$ model with the standard quartic Higgs potential. The mass of the scalar mode only appears in the quadratic part and not in the interaction vertices, unlike in the ordinary formulation of the theory. Renormalization of the model is discussed. A non power-counting renormalizable extension, obeying the defining functional identities of the theory, is…

We study the non-linear background field redefinitions arising at the quantum level in a spontaneously broken effective gauge field theory. The non-linear field redefinitions are crucial for the
Slavnov—Taylor Identities in Spontaneously Broken Non-Abelian Effective Gauge Theories
We study the solution to the Slavnov-Taylor identities in spontaneously broken effective gauge theories for a non-Abelian gauge group. The procedure to extract the β -functions of the theory in the
Off-shell renormalization in the presence of dimension 6 derivative operators. Part III. Operator mixing and β functions
We evaluate the one-loop $\beta$ functions of all dimension 6 parity-preserving operators in the Abelian Higgs-Kibble model. No on-shell restrictions are imposed; and the (generalized) non-polynomial
