Primordial black holes from spectator field bubbles
David Navidad Maeso, Luca Marzola, Martti Raidal +2
We study the evolution of light spectator fields in an asymmetric polynomial potential. During inflation, stochastic fluctuations displace the spectator field from the global minim…
Vacuum stability with radiative Yukawa couplings
Emidio Gabrielli, Luca Marzola, Kristjan Müürsepp +1
We explore the electroweak vacuum stability in the framework of a recently proposed paradigm for the origin of Yukawa couplings. These arise as low energy effective couplings radia…
A fake doublet solution to the muon anomalous magnetic moment
Damiano Anselmi, Kristjan Kannike, Carlo Marzo +5
Extensions to the Standard Model that use strictly off-shell degrees of freedom - the fakeons - allow for new measurable interactions at energy scales usually precluded by the cons…
Phenomenology of a Fake Inert Doublet Model
Damiano Anselmi, Kristjan Kannike, Carlo Marzo +5
We introduce a new way of modeling the physics beyond the Standard Model by considering fake, strictly off-shell degrees of freedom: the fakeons. To demonstrate the approach and ex…
Light Higgs boson from multi-phase criticality in dynamical symmetry breaking
Kristjan Kannike, Luca Marzola, Martti Raidal +1
The Coleman-Weinberg mechanism can realise different phases of dynamical symmetry breaking. In each phase a combination of scalars, corresponding to the pseudo-Goldstone boson of s…
Higgs-like spectator field as the origin of structure
Alexandros Karam, Tommi Markkanen, Luca Marzola +3
We show that the observed primordial perturbations can be entirely sourced by a light spectator scalar field with a quartic potential, akin to the Higgs boson, provided that the fi…
