Description
This study explores the parameter space of a minimal extension
of the Standard Model with a non-abelian SU(2) group, in which the gauge
bosons are stable and acquire mass through a mechanism of spontaneous
symmetry breaking involving a new scalar doublet which interacts with
the Higgs boson through a quartic coupling. The exploration aims to
assess whether it is possible to obtain a first-order phase transition
while ensuring that the gauge bosons are viable dark matter candidates.
Theoretical, astrophysical and collider bounds are considered. The
results are then tested against the sensitivity of future experiments
for the detection of gravitational wave signals.
