Displaced new physics at colliders and the early universe before its first second
Lorenzo Calibbi, Francesco D'Eramo, Sam Junius +2
Displaced vertices at colliders, arising from the production and decay of long-lived particles, probe dark matter candidates produced via freeze-in. If one assumes a standard cosmo…
Non-Cold Dark Matter from Primordial Black Hole Evaporation
Iason Baldes, Quentin Decant, Deanna C. Hooper +1
Dark matter coupled solely gravitationally can be produced through the decay of primordial black holes in the early universe. If the dark matter is lighter than the initial black h…
Variations in fundamental constants at the cosmic dawn
Laura Lopez-Honorez, Olga Mena, Sergio Palomares-Ruiz +2
The observation of space-time variations in fundamental constants would provide strong evidence for the existence of new light degrees of freedom in the theory of Nature. Robustly…
Strong dynamics and dark matter: investigating a minimal setup
Benjamin Fuks, Federica Giacchino, Laura Lopez-Honorez +2
We discuss the phenomenology of a dark matter scenario in which we extend the Standard Model by a real scalar particle and a vector-like heavy quark. Such a model can be seen as a…
A feeble window on leptophilic dark matter
Sam Junius, Laura Lopez-Honorez, Alberto Mariotti
In this paper we study a leptophilic dark matter scenario involving feeble dark matter coupling to the Standard Model (SM) and compressed dark matter-mediator mass spectrum. We con…
Dark Matter microphysics and 21 cm observations
Laura Lopez-Honorez, Olga Mena, Pablo Villanueva-Domingo
Dark matter interactions with massless or very light Standard Model particles, as photons or neutrinos, may lead to a suppression of the matter power spectrum at small scales and o…
