摘要
用短距离量子场论作指导,比较d-d,p-α,α-α与p-p碰撞中强子多重产生的实验数据,建立起相对论性的原子核外场的方位阱广函模型,对数型A依赖ln A~δ,解释了大量的强子-核与核-核碰撞数据:能量-动量分布,海鸥效应,各类多重数关联.质子场的反常维度2v_(F)（g_n）≈-1/ 4～（-2/ 3）,讨论了强子质壳问题.
Under the guiding of quantum field theory at short distance and by comparing the data of multihadron production in d-d, p-α, α-α and p-p collision, a square well model, in the form of generalised function, for the relativistic external field of nuclei is established. With the A-dependence of lnAδ, a lot of data of hadron-nucleus and nucleus-nucleus collisions, such as distribution of energy and momentum, seagull effect, different multiplicity correlations, are explained. The anomalous dimensionality of proton field is found, 2γF(gR}= - 1/4 ~ - 2/3. The problem of hadronic mass shell is also discussed.
