| 摘 要： | 利用400GeV/c pp碰撞多重产生的实验数据计算了粒子-粒子关联(PPC)及其不对称性(PPCA)的角度依赖性.结果与L3的e+e－数据有明显的差别,但与NA22强子碰撞的实验数据符合得很好;领头粒子对强子碰撞的PPCA分布有很大影响.通过计算两粒子方位角差的分布观察到了方位角关联.

| Abstract: | 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. |
