Sterile Neutrino Dark Matter Cries for GeV Heavy Neutral Leptons
Marco Drewes, Yannis Georis, Juraj Klarić +2
The ordinary and dark matter in the Universe may share a common origin in the framework of a minimal extension of the Standard Model by three right-handed neutrinos. A pair of such…
Consistent treatment of flavour-specific neutrino self-interactions in cosmology
Gabriela Barenboim, Marco Drewes, Isabel M. Oldengott
We study the impact of flavour-specific neutrino self-interactions on the CMB anisotropy spectrum and consistently take into account neutrino mixing. Starting from the neutrino qua…
Observing Cosmic Reheating with the expanded Simons Observatory
Lei Ming, Marco Drewes
The Simons Observatory will be extended by three Small Aperture Telescopes by 2027, increasing the total number of these instruments to six. We study the prospects for probing the…
Thermal effects on Dark Matter production during cosmic reheating
Marco Drewes, Yannis Georis, Mubarak A. S. Mohammed +1
The relic abundance of Dark Matter (DM) produced via thermal freeze-in is sensitive to the thermal history during and after cosmic reheating. In minimal models, this opens up the p…
Warm Inflation with the Standard Model
Kim V. Berghaus, Marco Drewes, Sebastian Zell
We show for the first time that warm inflation is feasible with Standard Model (SM) gauge interactions alone. Our model consists of a minimal extension of the SM by a single scalar…
Low-scale seesaw with flavour and CP symmetries $\unicode{x2013}$ from colliders to leptogenesis
Marco Drewes, Yannis Georis, Claudia Hagedorn +1
We consider an extension of the Standard Model with three right-handed neutrinos, endowed with a flavour symmetry , or , , and CP.…
Towards a precision calculation of in the Standard Model IV: Estimating the impact of positronium formation
Tobias Binder, Marco Drewes, Yannis Georis +3
We present a first assessment of how the previously unexplored effect of positronium formation can impact on the value of the effective number of neutrino species in the Standard M…
On the collider-testability of the type-I seesaw model with 3 right-handed neutrinos
Marco Drewes, Yannis Georis, Juraj Klarić +1
If any heavy neutral leptons are discovered in accelerator-based experiments, key questions will involve their possible connection to neutrino masses or leptogenesis. Working in a…
Towards a precision calculation of in the Standard Model III: Improved estimate of NLO contributions to the collision integral
Marco Drewes, Yannis Georis, Michael Klasen +2
We compute the dominant QED correction to the neutrino-electron interaction rate in the vicinity of neutrino decoupling in the early universe, and estimate its impact on the effect…
Upper Bound on Thermal Gravitational Wave Backgrounds from Hidden Sectors
Marco Drewes, Yannis Georis, Juraj Klaric +1
Hot viscous plasmas unavoidably emit a gravitational wave background, similar to electromagnetic black body radiation. We study the contribution from hidden particles to the diffus…
On Sphaleron Heating in the Presence of Fermions
Marco Drewes, Sebastian Zell
Axion-like particles with a coupling to non-Abelian gauge fields at finite temperature can experience dissipation due to sphaleron heating. This could play an important role for wa…
Feebly Interacting Particles: FIPs 2022 workshop report
C. Antel, M. Battaglieri, J. Beacham +75
Particle physics today faces the challenge of explaining the mystery of dark matter, the origin of matter over anti-matter in the Universe, the origin of the neutrino masses, the a…
Low-scale leptogenesis with flavour and CP symmetries
Marco Drewes, Yannis Georis, Claudia Hagedorn +1
We consider a type-I seesaw framework with a flavour symmetry from the series of non-abelian groups and and a CP symmetry. Breaking these symmetries non-trivi…
Sterile Neutrino Dark Matter
A. Boyarsky, M. Drewes, T. Lasserre +2
We review sterile neutrinos as possible Dark Matter candidates. After a short summary on the role of neutrinos in cosmology and particle physics, we give a comprehensive overview o…
