Is our vacuum global in a 331 model with three triplets?
Kristjan Kannike, Niko Koivunen, Aleksei Kubarski
We consider a 331 model, based on , with three triplets with a softly broken symmetry. The resulting scalar potential is commonly used in phen…

Dark matter in the scale-invariant 3-3-1-1 model
Alex G. Dias, Kristjan Kannike, Niko Koivunen +3
We propose a novel scale-invariant model with the 3-3-1-1 gauge symmetry featuring a universal see-saw mechanism for all fermion masses, which, through the inclusion of additional…

How deep is the dip and how tall are the wiggles in inflationary power spectra?
Vadim Briaud, Alexandros Karam, Niko Koivunen +3
We study linear scalar perturbations in single-field models of inflation featuring a non-attractor phase. These models lead to a peak in the curvature power spectrum that may resul…
