标题： Correlations and Fluctuations in High-Energy Nuclear Collisions

摘要： 靶核和弹核中的核子关联被证明可以显著减少相对论重离子碰撞中多重核子-核子碰撞、总粒子数和横向能量的涨落，尤其是在重弹核和重靶核的情况下。 从颜色透明性和不透明性产生的截面涨落与核关联之间的相互作用被计算出来，并发现能够解释横向能量谱中的大涨落。 讨论了在蒙特卡罗代码中关联和截面涨落的数值实现。 显示英文摘要

摘要： Nucleon correlations in the target and projectile nuclei are shown to reduce significantly the fluctuations in multiple nucleon-nucleon collisions, total multiplicity and transverse energy in relativistic heavy-ion collisions, in particular for heavy projectile and target. The interplay between cross-section fluctuations, from color transparency and opacity, and nuclear correlations is calculated and found to be able to account for large fluctuations in transverse energy spectra. Numerical implementation of correlations and cross-section fluctuations in Monte-Carlo codes is discussed.
