Abstract
The axion-like particle (ALP) is one kind of the best-motivated new particles. We consider its production from the pseudoscalar mesonic decays , with M being a pseudoscalar meson B or K. The upper limits on the flavor-conserving ALP–quark coupling parameter gu are obtained by assuming the ALP to be an invisible particle. We find that the most severe constraint on gu comes from the decay for 0.05 GeV ≤ Ma ≤ 0.35 GeV, while the decays and can also generate significant constraints.
