Heavy Dark Matter Through the Higgs Portal
John March-Russell, Stephen M. West, Daniel Cumberbatch +1
Motivated by Higgs Portal and Hidden Valley models, heavy particle dark matter that communicates with the supersymmetric Standard Model via pure Higgs sector interactions is consid…
Accounting for the Unresolved X-ray Background with Sterile Neutrino Dark Matter
Daniel Cumberbatch, Joseph Silk
We consider a scenario where keV sterile neutrinos constitute all of the currently inferred dark matter abundance, whose radiative decays could potentially account for the flux con…
Solving the cosmic lithium problems with primordial late-decaying particles
Daniel Cumberbatch, Kazuhide Ichikawa, Masahiro Kawasaki +3
We investigate the modifications to predictions for the abundances of light elements from standard Big-Bang nucleosynthesis when exotic late-decaying particles with lifetimes excee…
Dark Matter Searches: The Nightmare Scenario
Gianfranco Bertone, Daniel Cumberbatch, Roberto Ruiz de Austri +1
The unfortunate case where the Large Hadron Collider (LHC) fails to discover physics Beyond the Standard Model (BSM) is sometimes referred to as the "Nightmare scenario" of particl…
