Composite Dark Matter from Strongly-Interacting Chiral Dynamics
Roberto Contino, Alessandro Podo, Filippo Revello
A class of chiral gauge theories is studied with accidentally-stable pseudo Nambu-Goldstone bosons playing the role of dark matter (DM). The gauge group contains a vector-like dark…

Gluequark Dark Matter
Roberto Contino, Andrea Mitridate, Alessandro Podo +1
We introduce the gluequark Dark Matter candidate, an accidentally stable bound state made of adjoint fermions and gluons from a new confining gauge force. Such scenario displays an…

Bounds on Dark Matter decay from 21 cm line
Andrea Mitridate, Alessandro Podo
The observation of the cosmic 21-cm spectrum can serve as a probe for Dark Matter properties. We point out that the knowledge of the signal amplitude at a given redshift allows one…
