| dc.description.abstract | 摘要 利用色散关系研究了弱电流不守恒情况下的π-→π0+e+ν衰变过程。在对π—π散射相移作了一些假定后,证明了π、π中间态的贡献很小。在N、N中间态项中出现的N、N湮灭矩阵元用Chew-Ball理论及湮灭实验估计,同时出现的核子弱作用形状因子又用色散关系计算,证明了N、N中间态对它的贡献很小,计算了π、π中间态对它的贡献。根据现有N、N湮灭实验估计,π-→π0+e+ν过程的衰变几率-4秒-1。 Abstract The probability of π-→π0+e+ν decay in the case of non-conserved weak current is calculated with dispersion relation. After making certain assumptions about the π-π scattering phase shift, it is shown that the contribution of the π-π 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 | |
