The off-shell renormalization of spontaneously broken effective gauge theories is carried out
following the Algebraic Renormalization approach.
We provide a constructive way to obtain the canonical transformations with respect to
the Batalin-Vilkovisky bracket, associated with the gauge group of the theory, that
generalize the familiar linear field redefinitions arising in power-counting renormalizable theories.
By taking into account such generalized field redefinitions one can consistently extract the $\beta$-functions of the higher dimensional operators order by order in the loop expansion.
The gauge invariance of the ultraviolet coefficients for physical operators is explicitly checked at one loop order.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
