Challenges for a QCD axion at the 10 MeV scale
Abstract We report on an interesting realization of the QCD axion, with mass in the range O $$ \mathcal{O} $$ (10) MeV. It has previously been shown that although this scenario is stringently constrained from multiple sources, the model remains viable for a range of parameters that leads to an expla...
