-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…
Axion Dark Matter and additional BSM aspects in an extended 2HDM setup
Giorgio Arcadi, Sarif Khan
We illustrate and discuss the phenomenology of a model featuring a two-Higgs doublet sector augmented by two singlet scalars. The gauge symmetry group is extended as well w…
The 2HD+a model: collider, dark matter and gravitational wave signals
Giorgio Arcadi, Nico Benincasa, Abdelhak Djouadi +1
We perform a comprehensive study of a model in which the Higgs sector is extended to contain two Higgs doublet fields, with the four types of possibilities to couple to standard fe…
A model for fermionic dark matter addressing both the CDF and the anomalies
Giorgio Arcadi, Abdelhak Djouadi
We explore a simple and renormalizable model which incorporates a new stable fermion that accounts for the dark matter in the universe and which, at the same time, provides an inte…
Multicomponent Dark Matter from Gauge Symmetry
Giorgio Arcadi, Christian Gross, Oleg Lebedev +3
The composition of Dark Matter (DM) remains an important open question. The current data do not distinguish between single- and multi-component DM, while in theory constructions it…
Search for Dark Matter at Colliders
Francois Richard, Giorgio Arcadi, Yann Mambrini
Dark Matter (DM) detection prospects at future e+e- colliders are reviewed under the assumption that DM particles are fermions of the Majorana or Dirac type. Although the discussio…
