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
\gtrsim10^9 GeV). However, recent work has pointed out that viable axion models may also exist
for (f_a\sim1 GeV). In our research, we derive stringent constraints on this axion scenario from kaon
decay measurements.
