Is the Relaxion an Axion?
Rick S. Gupta, Zohar Komargodski, Gilad Perez +1
We consider the recently proposed cosmological relaxation mechanism where the hierarchy problem is ameliorated, and the electroweak scale is dynamically selected by a slowly rollin…
Heavy concerns about the light axino explanation of the 3.5 keV X-ray line
Stefano Colucci, Herbi K. Dreiner, Florian Staub +1
An unidentified 3.5 keV line from X-ray observations of galaxy clusters has been reported recently. Although still under scrutiny, decaying dark matter could be responsible for thi…
Dynamical generation of the Peccei-Quinn scale in gauge mediation
Guido Festuccia, Toby Opferkuch, Lorenzo Ubaldi
The Peccei-Quinn (PQ) mechanism provides an elegant solution to the strong CP problem. However astrophysical constraints on axions require the PQ breaking scale to be far higher th…
