Therefore in terms of relativistic heavy ion collisions it is possible for quark and gluon to deconfine in wider range and form quark - gluon plasma . the initial consideration of j / ? suppression in deconfined medium is based on color screening 相对论性重离子碰撞实验是用高能加速器把重离子加速到很高能量实现重离子与重离子的碰撞,从而有可能在一个相对较大的范围解除夸克、胶子的禁闭,形成qgp 。
