量子场反常维度与相对的质量效应
Anomalous dimension of quantum fields and relative mass effects
【摘要】 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;由玻色量子场反常维度γB(gR)而确定的质量反常维度γm(gR)=-2πγB(gR)/3与实验吻合,是质量效应存在的强有力证据;扣除相对的质量效应,以xN=(N-αab)/(〈N〉-αab)为自变量拟合的分布曲线,与实验符合较好。
【Abstract】 Distrbutions the anomalous dimensions of the pionic quantum fields are γB(gR)=-0.045±0.012,which control the singularities of the production amplitude in quantum field theory;The anomalous dimension of mass, γm(gR)=-2πγB(gR)/3 determined by γB(gR)—the anomalous dimension of Bose quantum fields, agrees with experiments, this is the strong evidence of the existence of the mass effects; The conclusion is that the multiplicity distribution using xN=(N-αab)/(〈N〉-αab) as its variable agrees with experimental data fairly well after making subtraction of the relative mass effects.
【Key words】 anomalous dimension of quantum fields; singularities of production amplitude; anomalous dimension of mass; relative mass effects;
