A unitary and renormalizable model for massive Yang-Mills fields without
Higgs fields    [PDF]

Kei-Ichi Kondo

We propose a massive Yang-Mills model blessed with both physical unitarity
and renormalizability without Higgs particles. This is achieved by a novel
nonlinear but local transformation from the original fields in the
Curci-Ferrari model to the massive vector field with the spin one, which has
the correct physical degrees of freedom and invariant under an extended BRST
transformation. We clarify the reason for failures of the preceding attempts
and check the physical unitarity in perturbation theory.
