Pion dark matter in a vacuum: a thermal relic with sharp velocity-dependent self-interactions
Camilo García-Cely, Giacomo Landini, Luca Marsili +1
As recently proposed, a non-vanishing topological angle may play a central role in QCD-like theories of dark matter (DM). In this work, we introduce a dark photon portal to the Sta…
Dark Matter in an Evanescent Three-Brane Randall-Sundrum Scenario
Andrea Donini, Miguel G. Folgado, Juan Herrero-García +3
Apart from its gravitational interactions, dark matter (DM) has remained so far elusive in laboratory searches. One possible explanation is that the relevant interactions to explai…
High-quality Peccei-Quinn symmetry from the interplay of vertical and horizontal gauge symmetries
Luca Di Luzio, Giacomo Landini, Federico Mescia +1
We explore a class of axion models where an accidental Peccei-Quinn (PQ) symmetry automatically emerges from the interplay of vertical (grand-unified) and horizonta…
Optical gravitational waves as signals of Gravitationally-Decaying Particles
Giacomo Landini, Alessandro Strumia
Long-lived heavy particles present during the big bang could have a decay channel opened by gravitons. Such decays can produce gravitational waves with large enough abundance to be…
