Description
The QCD axion is a compelling mechanism for solving the strong CP problem. Most studies have focused on axion models with a large decay constant, $(f_{a}\gtrsim 10^{9}\,\mathrm{GeV})$. However, recent work has pointed out that viable axion models may also exist for $(f_{a}\sim1\,\mathrm{GeV}$). In our research, we derive stringent constraints on this axion scenario from kaon decay measurements.
