Preheating in an Asymptotically Safe Quantum Field Theory
Ole Svendsen, Hossein Bazrafshan Moghaddam, Robert Brandenberger
We consider reheating in a class of asymptotically safe quantum field theories recently studied in \cite{Litim:2014uca, Litim:2015iea}. These theories allow for an inflationary pha…
Inflation from Asymptotically Safe Theories
Niklas Grønlund Nielsen, Francesco Sannino, Ole Svendsen
We investigate models in which inflation is driven by an ultraviolet safe and interacting scalar sector stemming from a new class of nonsupersymmetric gauge field theories. These n…
Marginally Deformed Starobinsky Gravity
A. Codello, J. Joergensen, F. Sannino +1
We show that quantum-induced marginal deformations of the Starobinsky gravitational action of the form , with the Ricci scalar and a positive parameter, smalle…
Primordial tensor modes from quantum corrected inflation
Jakob Joergensen, Francesco Sannino, Ole Svendsen
We analyze quantum corrections on the naive -Inflation. These typically lead to an inflaton potential which carries a non-integer power of the field. We consider both minimal…
X-ray Lines from Dark Matter: The Good, The Bad, and The Unlikely
Mads Frandsen, Francesco Sannino, Ian M. Shoemaker +1
We consider three classes of dark matter (DM) models to account for the recently observed 3.5 keV line: metastable excited state DM, annihilating DM, and decaying DM. We study two…
LUX Constraints on Magnetic Dark Matter in the y Model with(out) Naturality
Mads T. Frandsen, Francesco Sannino, Ian M. Shoemaker +1
We study phenomenological constraints in a simple y extension of the Standard Model (SM) with a 125 GeV Higgs, a vector-like heavy electron , a complex scalar elec…
