摘要
非微扰(短距离) 量子场论的横动量标度分布Q- v⊥ Kν(β⊥ Q⊥/〈Q⊥〉) 与实验数据( S= 5 ~1 800GeV)符合得很好,在固定多重数N 用快度截断技术后的质量证认数据( 单个强子源, S= 1 800 GeV) 与低能p⊥- 分布重合( S= 5GeV) ,低能p⊥- 分布反常的困难消失.这里量子场反常维度-2 γB( gR) = 0 .084±0 .002 (αs = 0 .126 ±0.003 ,QCD).强子源的相对论性多普勒(Doppler)效应存在,而标度律仍然成立.
The mass identified data ( S =5—1800?GeV) of the scaling ( p ⊥/〈 p ⊥〉) distributions are reproduced by the nonperturbation theory of quantum fields (at short distance).Using the rapidity cut techniqu at fixed multiplicity N the p ⊥/〈 p ⊥〉 distribution at S =5?GeV is coincided with that of a hadrom source at S =1?800?GeV,where -2γ B (g R )=0.084±0.002 (α S=0.126±0.003,QCD).The difficult of the anomalous low p ⊥ distribution disappears.The relativistic Doppler's effects of the hadron source exist and the momentum scaling also holds.
