最近,人们对标度函数又有了新的兴趣,而且兴趣越来越大[1,2]。在这个领域中最值得注意的发展之一是σ(600)在20年后的重新鉴定。对散射(S)矩阵的π-π散射相移的再分析结果强烈地表明了I = 0和J = 0的σ介子的极点的存在
Recently there has been renewed and growing interestin scalarmesons[1, 2]. Oneofthe mostnoteworthydevel-opments in this field is the re-identification of the σ(600)after some twenty years. The results of re-analyses of theπ-π scattering phase shift of the scattering (S) matrixstrongly suggest the existence of the pole of the σ mesonwith I = 0 and J
