Reduced Axion Abundance from an Extended Symmetry
Itamar J. Allali, Mark P. Hertzberg, Yi Lyu
In recent work we showed that the relic dark matter abundance of QCD axions can be altered when the Peccei-Quinn (PQ) field is coupled to very light scalar/s, rendering the effecti…

Altered Axion Abundance from a Dynamical Peccei-Quinn Scale
Itamar J. Allali, Mark P. Hertzberg, Yi Lyu
We build a model in which the relic abundance of axions is altered from the standard misalignment mechanism, either increased or decreased, due to the presence of a new light scala…
