利用强子-强子碰撞的PYTHIA模型,模拟了质心系能量为√s=22，200GeV的质子-质子碰撞。研究了快度空间中末态粒子在固定bin和任意bin中,以及相邻bin中的关联花样。结果发现,相邻bin的快度关联在中心快度区最强，向边缘区逐渐减弱;固定bin和任意bin的关联在固定bin取不同快度位置时，具有不同的花样。

Proton-proton collisions at root s = 22 GeV and 200 GeV have been simulated by PYTHIA model. The fixed-to-arbitrary and neighboring bin correlation patterns at these two colliding energies are investigated. It has been found that the neighboring bin correlations are the strongest at the central rapidity region and become weaker and weaker toward the two side rapidity regions;while the fixed-to-arbitrary bi...
