The LHC diphoton resonance and dark matter
Yann Mambrini, Giorgio Arcadi, Abdelhak Djouadi
A Higgs-like resonance with a mass of approximately 750 GeV has recently been observed at the LHC in its diphoton decay. If this state is not simply a statistical fluctuation which…
Dark Matter and Baryon Asymmetry production from out-of-equilibrium decays of Supersymmetric states
Giorgio Arcadi
We will review the main aspects of a mechanism for the contemporary generation of the baryon and Dark Matter abundances from the out-of-equilibrium decay of a Wimp-like mother part…
Dark Matter phenomenology of GUT Inspired simplified models
Giorgio Arcadi
We discuss some aspects of dark matter phenomenology, in particular related to Direct detection and collider searches, of models in which a fermionic Dark Matter interacts with SM…
Impact of Dark Matter Direct and Indirect Detection on Simplified Dark Matter Models
Giorgio Arcadi, Yann Mambrini, Mathias Pierre
We discuss simple extensions of the Standard Model featuring a (fermionic) stable DM candidate interacting with SM fermions through a mediator. These kind of models offer a…
Gravitino Dark Matter and low-scale Baryogenesis
Giorgio Arcadi, Laura Covi, Marco Nardecchia
A very simple way to obtain comparable baryon and DM densities in the early Universe is through their contemporary production from the out-of-equilibrium decay of a mother particle…
Lepton number violation as a key to low-scale leptogenesis
Asmaa Abada, Giorgio Arcadi, Valerie Domcke +1
We explore the possibility of having a successful leptogenesis through oscillations between new sterile fermion states added to the Standard Model field content in a well motivated…
