Dark Particles at the LHC: LHC-Friendly Dark Matter Characterization via Non-Linear EFT
Giorgio Arcadi, David Cabo-Almeida, Sven Fabian +1
In this work we illustrate a general framework to describe the LHC phenomenology of extended scalar (and fermion) sectors, with focus on dark matter (DM) physics, based on an effec…
-mediated dark matter freeze-in at stronger coupling
Giorgio Arcadi, David Cabo-Almeida, Oleg Lebedev
We study freeze-in production of fermionic dark matter mediated by a gauge boson. In particular, we explore the regime of Boltzmann-suppressed production, when the Stand…
Ultraheavy Dark Matter and WIMPs Production aided by Primordial Black Holes
Giorgio Arcadi, Manfred Lindner, Jacinto P. Neto +1
The unitary bound restricts thermal relics to be lighter than TeV. This work investigates the production of ultraheavy dark matter and WIMPs in the presence of primordial bla…
Thermal and non-thermal DM production in non-Standard Cosmologies: a mini review
Giorgio Arcadi
We provide a short review of some aspects of Dark Matter production in non Standard Cosmology. Considering the simplest Higgs portal model as definite particle physics setup, we co…
Higgs Portal Dark Matter Freeze-in at Stronger Coupling: Observational Benchmarks
Giorgio Arcadi, Francesco Costa, Andreas Goudelis +1
We study freeze-in production of Higgs portal dark matter (DM) at temperatures far below the dark matter mass. The temperature of the Standard Model (SM) thermal bath may have neve…
The Waning of the WIMP: Endgame?
Giorgio Arcadi, David Cabo-Almeida, Maíra Dutra +7
Weakly Interacting Massive Particles (WIMPs) continue to be considered some of the best-motivated Dark Matter (DM) candidates. No conclusive signal, despite an extensive search pro…
