We study a variant of Gauge-flation where the gauge symmetry is spontaneously broken by a Higgs sector .
We work in the Stueckelberg limit and demonstrate that the dynamics remain ( catastrophically ) unstable for cases where the gauge field masses satisfy \gamma < 2 , where \gamma = g ^ { 2 } \psi ^ { 2 } / H ^ { 2 } , g is the gauge coupling , \psi is the gauge field vacuum expectation value , and H is the Hubble rate .
We compute the spectrum of density fluctuations and gravitational waves , and show that the model can produce observationally viable spectra .
The background gauge field texture violates parity , resulting in a chiral gravitational wave spectrum .
This arises due to an exponential enhancement of one polarization of the spin-2 fluctuation of the gauge field .
Higgsed Gauge-flation can produce observable gravitational waves at inflationary energy scales well below the GUT scale .
