About
The axion is one of the most compelling candidates for physics beyond the Standard Model, as it simultaneously provides a solution to the strong CP problem and a viable dark matter candidate. In post-inflationary scenarios, the minimal QCD axion model leads to strong constraints on the axion mass from the dark matter relic abundance. Specific quantization relations hold for the axion-gauge couplings which constrain further the parameter space. In this work, we test how robust these phenomenological features are in multiple-axion scenarios. Considering a two-axion framework, we explore whether new regions of parameter space remain theoretically and phenomenologically motivated.
