The price for monopole dark matter
Felix Brümmer, Giacomo Ferrante, Théodore Fischer +1
We construct an explicit model where dark matter consists of 't Hooft-Polyakov monopoles. The dark sector is in thermal contact with the Standard Model, and dark monopoles are crea…

No room for minimal monopole dark matter
Felix Brümmer, Giacomo Ferrante, Théodore Fischer +1
The magnetic monopole of a dark sector has been advocated as an appealing dark matter candidate. We revisit the computation of the monopole abundance , generated by a thermal…

Hybrid inflation and gravitational waves from accidentally light scalars
Felix Brümmer, Giacomo Ferrante, Michele Frigerio
We construct a hybrid-inflation model where the inflaton potential is generated radiatively, as gauge symmetries guarantee it to be accidentally flat at tree level. The model can b…
