Abstract

NA22 experimental data of the triplet seagull effects show that the Doppler effects of the hadron emission sources exist exactly in the hadron-hadroncollisions. Every source possesses the same average energy (CMS) approximately. The collective seagulleffects can be also explained by the (aQ)K-nu(nu) (aQ) distributions (Generalized functions). The dynamical structure of ahadron emission source is discribed by the (aQ)K-nu(nu) (aQ) distributions. The anomalous dimensions of the pionic quantum fields are gamma (B)(g(R))= -0. 045 +/- 0. 012, which control the singularities of the production amplitude in quantum field theory. The mathematical parameter epsilon = 4 - D(the dimension D of space time) in the Feynman integrals can be replaced by the anomalous YB(gR) Of the quantum fields for the regularization. ( -2 gamma (B)(gR) <----> epsilon /2 = 1/ln(Lambda (2)/m(2))Lambda->infinity).
