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…
Accidentally light scalars from large representations
Felix Brümmer, Giacomo Ferrante, Michele Frigerio +1
In models with spontaneous symmetry breaking by scalar fields in large group representations, we observe that some of the scalar masses can be loop-suppressed with respect to the n…
Coscattering in next-to-minimal dark matter and split supersymmetry
Felix Brümmer
In some models of thermal relic dark matter, the relic abundance may be set by inelastic scattering processes (rather than annihilations) becoming inefficient as the universe cools…
Next-to-minimal dark matter at the LHC
Aoife Bharucha, Felix Brümmer, Nishita Desai
We examine the collider signatures of a WIMP dark matter scenario comprising a singlet fermion and an SU(2) n-plet fermion, with a focus on n=3 and n=5. The singlet and n-plet mass…
