UltraViolet Freeze-in
Fatemeh Elahi, Christopher Kolda, James Unwin
If dark matter is thermally decoupled from the visible sector, the observed relic density can potentially be obtained via freeze-in production of dark matter. Typically in such mod…
Towards Cogenesis via Asymmetric Freeze-in: The Who Came-in from the Cold
James Unwin
In models of freeze-in the dark matter (DM) is decoupled from the visible sector and initially has a depleted number density. The hidden and visible sectors are connected only via…
Precision Unification and Proton Decay in F-Theory GUTs with High Scale Supersymmetry
Arthur Hebecker, James Unwin
F-theory GUTs provide a promising UV completion for models with approximate gauge coupling unification, such as the (non-supersymmetric) Standard Model. More specifically, if the s…
Fitting the Galactic Center Gamma-Ray Excess with Cascade Annihilations
Adam Martin, Jessie Shelton, James Unwin
The apparent excess of gamma rays in an extended region in the direction of the galactic center has a spatial distribution and amplitude that are suggestive of dark matter annihila…
X-ray lines from R-parity violating decays of keV sparticles
Christopher Kolda, James Unwin
If R-parity is only mildly violated then the lightest supersymmetric particle (LSP) can be stable over cosmologically time-scales and still account for the dark matter relic densit…
Annihilation Signals from Asymmetric Dark Matter
Edward Hardy, Robert Lasenby, James Unwin
In the simplest models of asymmetric dark matter (ADM) annihilation signals are not expected, since the DM is non-self-conjugate and the relic density of anti-DM is negligible. We…
