摘要
利用４００ＧｅＶ／ｃｐｐ碰撞多粒子产生的实验数据计算了ＱＣＤ分支过程的熵指数，得到了非零值，熵指数随末态粒子平均多重数的减小而增大。表明在４００ＧｅＶ／ｃｐｐ碰撞中有存在混沌性的迹象。
The entropy indices of QCD branching process are calculated from the data of 400GeV/ c pp collisions. The nonzero values of entropy indices are obtained. The entropy indices are increased with decreasing average multiplicity's of the final states. It means that the is a chaotic sign in pp collisions at 400GeV/c.
