R. Casalbuoni et al., NEW VECTOR BOSONS IN THE ELECTROWEAK SECTOR - A RENORMALIZABLE MODEL WITH DECOUPLING, Physical review. D. Particles and fields, 56(9), 1997, pp. 5731-5747
A linear realization of a model of dynamical electroweak symmetry brea
king describing additional heavy vector bosons is proposed. The model
is a SU(2)(L)xU(1)xSU(2)(L)'xSU(2)(R)' gauge theory, breaking at some
high scale u to SU(2)(weak)xU(1)(Y) and breaking again in the standard
way at the electroweak scale upsilon to U(1)(em). The model is renorm
alizable and reproduces the standard model in the limit u --> infinity
. This decoupling property is shown to hold also at the level of radia
tive corrections by computing, in particular, the epsilon parameters.
