Statistical Analyses of Higgs- and Z-Portal Dark Matter Models
John Ellis, Andrew Fowlie, Luca Marzola +1
We perform frequentist and Bayesian statistical analyses of Higgs- and Z-portal models of dark matter particles with spin 0, 1/2 and 1. Our analyses incorporate data from direct de…
Constant-Roll (Quasi-)Linear Inflation
Alexandros Karam, Luca Marzola, Thomas Pappas +2
In constant-roll inflation, the scalar field that drives the accelerated expansion of the Universe is rolling down its potential at a constant rate. Within this framework, we highl…
Search for Dark Matter Effects on Gravitational Signals from Neutron Star Mergers
John Ellis, Andi Hektor, Gert Hütsi +4
Motivated by the recent detection of the gravitational wave signal emitted by a binary neutron star merger, we analyse the possible impact of dark matter on such signals. We show t…
Oscillating Spin-2 Dark Matter
Luca Marzola, Martti Raidal, Federico R. Urban
We show that the coherent oscillations of a spin-2 field from bimetric theory can easily account for the observed dark matter abundance. We obtain the equation of motion for the fi…
Minimal flavor-changing models and muon after the measurement
Stefano Di Chiara, Andrew Fowlie, Sean Fraser +4
There has been a steady interest in flavor anomalies and their global fits as ideal probes of new physics. If the anomalies are real, one promising explanation is a new gauge…
Single Field Double Inflation and Primordial Black Holes
Kristjan Kannike, Luca Marzola, Martti Raidal +1
Within the framework of scalar-tensor theories, we study the conditions that allow single field inflation dynamics on small cosmological scales to significantly differ from that of…
Phase transition and gravitational wave phenomenology of scalar conformal extensions of the Standard Model
Luca Marzola, Antonio Racioppi, Ville Vaskonen
Thermal corrections in classically conformal models typically induce a strong first-order electroweak phase transition, thereby resulting in a stochastic gravitational wave backgro…
Gamma-ray line constraints on Coy Dark Matter
Andi Hektor, Luca Marzola, Taavi Tuvi
Coy dark matter is an effective scheme in which a fermionic dark matter candidate interacts with the Standard Model fermions via a pseudoscalar mediator. This simple setup avoids t…
