The fractal behaviour of multiplicity production in 400 GeV/c pp collisions is analyzed using the modified multifractal moments.The generalized dimensions Dq,q=2—5,are calculated.A comparison with the results obtained by the method of scaled factorial moments has been made. The results show that the multifractal character is observed.The fractal analysis method proposed by Fujio Takagi has been tested. 相似文献

The production mechanism of ring-like events has been investigated by using the data of pseudorapidity distribution of charged particles produced in pp collisions at 400GeV/c. The results show that the model of coherent gluon emission within a finite region of space-time is a possible production mechanism of ring-like events, but certainly not dominant. 相似文献

利用分形来研究高能碰撞多粒子产生机制是新兴的交叉科学,而获取多粒子产生的多重分形谱对了解高能碰撞机制很重要.本文将改进的连续阶数阶乘矩方法应用于40 0GeV/cpp碰撞多重产生的自仿射分析中,首次得到了自仿射多重分形谱. 相似文献

A Self-affine fractality analysis was performed by using the experimental data of multiparticle production in pp collisions at 400GeV/c. Compared with the results obtained from the selfsimilar analysis, the self-affine fractality analysis shows a better scaling behavior within the limits of the experimenal resolution. 相似文献

对400GeV/c pp碰撞多粒子产生的实验数据作了不稳定性分析.计算了新的不稳定性参数.将它们与曹珍和华家照利用软相互作用模型ECOMB模拟NA22能量范围的强子一强子碰撞实验所得到的结果相比较,相似性清楚可见.这表明ECOMB模型是一个软相互作用多粒子产生模型.它能重现高能强子碰撞末态事例结构的涨落. 相似文献

The angular dependence of the particle-Particle comeladon (PPC) and its asytiumeby (PPCA) have been calculated by using the experimental data of multiplicity production for pp collisions at 400GeV/ c. The results are different stmngly from the overall behavior of e+e- data,but agree with the results obtained by NA22 collaboration quite well. The leading particles influence stingily the PPCA disribibudons for hadronic collisions data. The calculated results for the distributions of the azimuthal difference between two pardcles mean that the azimuthal correlation has been observed. 相似文献
