Collider and direct detection as key probes of asymmetric dark matter: Signals from a compressed Inert Higgs doublet
David Cerdeño, Miguel Escudero, Pietro Ghedini +4
The cosmic imbalance of particles over antiparticles may be inherited by the dark matter in a certain class of asymmetric dark matter models. In this article, we thoroughly investi…
Probing the neutrino chemical potential with cosmological observations
Pietro Ghedini, Riccardo Impavido, Stefano Gariazzo +2
The electron neutrino degeneracy parameter, , is tightly constrained by Big Bang Nucleosynthesis (BBN), while the degeneracy parameters of…
Dark energy and neutrinos along the cosmic expansion history
Pietro Ghedini, Rasmi Hajjar, Olga Mena
Recent cosmological measurements are hinting that dark energy may evolve, with its equation of state, , even showing oscillatory patterns. In this work, we employ a…
Redshift Space Distortions corner interacting Dark Energy
Pietro Ghedini, Rasmi Hajjar, Olga Mena
Despite the fact that the CDM model has been highly successful over the last few decades in providing an accurate fit to a broad range of cosmological and astrophysical observat…
