Probing the muon with future beam dump experiments
Rupert Coy, Xun-Jie Xu
We consider the light explanation of the muon anomaly. Even if such a has no tree-level coupling to electrons, in general one will be induced at loop-level. We show…
The domain of thermal dark matter candidates
Rupert Coy, Thomas Hambye, Michel H. G. Tytgat +1
We consider, in general terms, the possible parameter space of thermal dark matter candidates. We assume that the dark matter particle is fundamental and was in thermal equilibrium…
Seesaw determination of the dark matter relic density
Rupert Coy, Aritra Gupta, Thomas Hambye
In this article, we show that in the usual type-I seesaw framework, augmented solely by a neutrino portal interaction, the dark matter (DM) relic density can be created through fre…
Neutrino lines from DM decay induced by high-scale seesaw interactions
Rupert Coy, Thomas Hambye
If the stability of the dark matter (DM) particle is due to an accidental symmetry, nothing prevents UV physics from destabilising it by inducing DM decays suppressed by powers of…
New physics in transitions at one loop
Rupert Coy, Michele Frigerio, Federico Mescia +1
We investigate new-physics contributions to transitions in the context of an effective field theory extension of the Standard Model, including operator mixing at…
Dynamical Clockwork Axions
Rupert Coy, Michele Frigerio, Masahiro Ibe
The clockwork mechanism is a novel method for generating a large separation between the dynamical scale and interaction scale of a theory. We demonstrate how the mechanism can aris…
