| 摘 要： | 本文分析了~(16)O(14.6和200AGeV)和~(32)S(200A GeV)离子诱导核乳胶相互作用中,在前后赝快度窗口内的多重数之间的关联.结果发现,核—校碰撞的前后多重数关联随着能量和射弹尺寸的增加而增加,随着间隔的增加而减小,随着窗口的扩大,关联缓慢的增加并趋于饱和.文章还比较了质子—质子和质子—核碰撞的数据.

| Abstract: | Correlations between multiplicities in forward and backward pseudo-rapidity windows eith gap in oxygen(at 14.6 and 200A GeV)and sulphur(at 200 A GeV)inos induced nuclear emulsion interac- tions are analyzed.We find that the correlation strength in nucleus-nucleus collisions increases with in- craeasing energy and size of projectile,decreases with increasing gap,and very slowly increases and then saturtes with enlarging window,Comparisions with date of proton-proton and proton-nucleus collision are alse made. |
