Within the framework of a factorization model, we study the behaviour of nuclear modification factor in Au-Au collisions at RHIC and Pb-Pb collisions at LHC. We find that the nuclear modification factor is inversely proportional to the radius of the quark-gluon plasma and is dominated by the surface emission of hard jets. We predict the nuclear modification factor PLHS AA ∼ 0.15 in central Pb-Pb collisions at LHC. The study shows that the factorization model can be used to describe the centrality dependence of nuclear modification factor of th...

在一个因式分解模型的框架以内，我们在 LHC 在 RHIC 和 Pb Pb 碰撞在 Au Au 碰撞学习原子修正因素的行为。我们发现原子修正因素与 quark-gluon 血浆的半径相反地成正比并且被难喷气的表面排放统治。我们预言原子修正因素 P LHS AA ~ 0.15 在在 LHC 的中央 Pb Pb 碰撞。因式分解模型能习惯于的学习表演描述在 RHIC 和 LHC 在重离子碰撞生产的高横向的动量粒子的原子修正因素的中心性依赖。
