We present the quantum mechanically honest description of unstable particles. Wedemonstrate it by taking the short-lived neutral A-meson A. as an example. A. can bedescribed properly as a nn resonance. This view will be explicitly shown based upon atoy model which allows exact stationary nn scattering solutions at any fixed energy.All our results can easily be extended to cases of realistic unstable particles. Notably itwill be shown that the weak interactions responsible to particle decays are dominatingat resonances (decaying particles), where strong interactions play minor roles (and areregarded as small perturbation terms there). In other words, weak interactions exhibitnon-perturbative effects at resonance regions.
