作为手征微扰论的推广,手征么正法不仅自由参量少,而且又能很好地解释更高能的实验,特别是共振态的出现。对J/Ψ→■*0(892)K+π-衰变过程的计算,其结果与实验较为符合,重现了K*0(892)共振态过程。
As a generalization of chiral perturbation theory, the chiral positive method not only has fewer free parameters, but also can explain the higher energy experiments well, especially the appearance of resonance states. The calculation of J + Ψ → ■ * 0 (892) K + π-decay process is in good agreement with the experiment and reproduces the K * 0 (892) resonant state process.
