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.
