Dirac vs Majorana gauginos at a 100 TeV collider
Giovanni Grilli di Cortona, Edward Hardy, Andrew J. Powell
We compare the prospects for observing theories with Majorana or Dirac gauginos at a future 100 TeV proton-proton collider. Calculating the expected discovery and exclusion regions…
Galaxy Cluster Thermal X-Ray Spectra Constrain Axion-Like Particles
Joseph P. Conlon, M. C. David Marsh, Andrew J. Powell
Axion-like particles (ALPs) and photons inter-convert in the presence of a magnetic field. At keV energies in the environment of galaxy clusters, the conversion probability can bec…
A 3.55 keV line from : predictions for cool-core and non-cool-core clusters
Joseph P. Conlon, Andrew J. Powell
We further study a scenario in which a 3.55 keV X-ray line arises from decay of dark matter to an axion-like particle (ALP), that subsequently converts to a photon in astrophysical…
Loop corrections to Delta N_eff in large volume models
Stephen Angus, Joseph P. Conlon, Ulrich Haisch +1
In large volume models reheating is driven by the decays of the volume modulus to the visible sector, while the decays to its axion partners result in dark radiation. In this artic…
