| Abstract: In this talk, I will show that the QCD axion, originally proposed to solve the strong CP problem, can also account for the baryon asymmetry when considering its interactions with magnetic monopoles. Next, I will introduce a simple dark axion–monopole model in which the axion dynamics induces an effective interaction between dark matter and dark energy. These models further strengthen the motivation for the QCD axion and axion-like particles. |
