摘要
ＮＡ２２的π介子三重海鸥效应指出，强子发射源的Ｄｏｐｐｌｅｒ效应确实存在．在质心系（ＣＭＳ）中三个强子发射源的平均能量近似相等．每个强子发射源的动力学结构由（αＱ）νＫν。（ αＱ）分布刻画．单个强子发射源中π介子的反常维度为－ γＢ（ｇＲ）＝ ０．０４５±０．０１２，这个物理量控制粒子产生幅的奇异性．
NA22 experimental data of the triplet seagull effects show that the Doppler effects of the hadron emission sources exist exactly in the hadron-hadron collisions. Every source possesses the same average energy (CMS) approximately. The collective seagulleffects can be also explained by the (aQ )vKv (aQ ) distributions (Generalized functions). The dynamical structure of a hadron emission source is discribed by the (aQ )vKv (aQ ) distributions. The anomalous dimensions of the picnic quantum fields are rB (gR ) = - 0.045 ± 0. 012, which control the singularities of the production amplitude in quantum field theory. The mathematical parameter = 4 - D (the dimension D of space time) in the Feynman integrals can be replaced by the anomalous rB (gR ) of the quantum fields for the regularization. (- 2rB (gR ) /2 = 1/1n(A2/m2 )A→∞ ).
