We summarize, in this proceedings,
our analysis for the vacuum stability of the superweak extension of the standard model.
The parameter space allowed by the $W$-boson mass measurements and collider searches for a new scalar particle are also presented.
The final result is a well defined non-vanishing portion of the parameter space, where the vacuum is stable, the couplings are perturbative and is not excluded by $W$ mass measurements and collider searches.

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.
