THE RADIATIVE DECAY OF AN ω PARTICLE

Abstract

摘要 本文由质量的解析延拓得到ω→π+r过程的色散关系,讨论了某些有关不稳定粒子色散关系的问题。在一些简化假设下得到Wω→π+r/Wω→3π≈0.35。在η粒子与ω粒子量子数相同的情形下得到Wη→π+r/Wη→3π≈25,在计算中包含了三个π介子成对作用的效应。 Abstract A dispertion relation for the process ω→π+γ is obtained by the analytical continuation in the ω mass. Some problems concerning dispertion relations involving unstable particles arc discussed. Under simplified assumptions we obtain Wω→π+r/Wω→3π≈0.35 and Wη→π+r/Wη→3π≈25, if η has the same quantum numbers as ω. The effect of the interaction in pairs between three pions is included in the calculation. 作者及机构信息 戴元本 1. 中国科学院 Authors and contacts DAI YUAN-BEN 1. 中国科学院 参考文献 [1] 施引文献
