Superhorizon enhancement of the hydrodynamic GW tail in Standard Model embedded warm inflation
Simone Biondini, M. Laine
Hydrodynamic fluctuations in the primordial plasma generate a gravitational-wave (GW) background that grows like in terms of the current frequen…
Dark matter bound states made easy
Simone Biondini, Stefan Vogl
A light force carrier can mediate long-range interactions between dark matter particles and facilitate the formation of bound states. Models incorporating these features have attra…
A critical look at low-scale cosmological phase transitions in the PTA era
Simone Biondini, Philipp Schicho
Motivated by the recent evidence for a stochastic gravitational-wave (GW) background reported by pulsar timing array (PTA) collaborations, we perform a precision study of low-scale…
Charting the Flavour Structure of Dark Matter
Simone Biondini, Admir Greljo, Xavier Ponce Díaz +1
What flavour structure of -channel thermal dark matter remains compatible with current flavour physics and direct detection bounds? We broadly chart the space of hypotheses usin…
Connecting -channel Dark Matter Models to the Standard Model Effective Field Theory
Simone Biondini, Lorenzo Tiberi, Orlando Panella
We investigate the connection between simplified dark matter models featuring a -channel scalar mediator and the Standard Model Effective Field Theory (SMEFT). We focus on scena…
Computing singlet scalar freeze-out with plasmon and plasmino states
S. Biondini, M. Eriksson, M. Laine
The final-state particles from cosmological dark matter co-annihilation are expected to equilibrate. As dictated by Hard Thermal Loop resummation, the spectrum of equilibrated quas…
