Axion global fits with Peccei-Quinn symmetry breaking before inflation using GAMBIT

Axion global fits with Peccei-Quinn symmetry breaking before inflation using GAMBIT

Abstract We present global fits of cosmologically stable axion-like particle and QCD axion models in the mass range 0.1 neV to 10 eV. We focus on the case where the Peccei-Quinn symmetry is broken before the end of inflation, such that the initial value of the axion field can be considered to be hom...
