Characterizing LHC-Resonances in extended HEFT: information on the nature of extended scalar sectors
Giorgio Arcadi, David Cabo-Almeida, Florian Goertz +1
In theories with extended scalar sectors the lightest new scalar degree of freedom might be accessible at colliders. Going beyond simplified models, such a theory can be described…

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…
