摘要
对高能重离子碰撞中有夸克-胶子等离子体(QGP)形成时的多粒子玻色-爱因斯坦关联进行了分析.通过考查多π关联平均强度随事件π多重数的变化表明,当有QGP产生时,多π关联平均强度在某一高多重数区域会有明显的上升;这种信号能够敏感地检测在高能重离子碰撞中少数有QGP形成的高π多重数事件.
The multiparticle Bose-Einstein correlations for formation of quark-gloun plasma (QGP) in high energy heavy ion collisions are analysed. Investigating the average correlation intensities of multipions as a function of pion multiplicity indicats that they have obvious enhancements in the high multiplicity region. This signature can be used to detect the existence of QGP in rare high-pion-multiplicity events sensitively in high energy heavy ion collisions.
