摘要:

奇异粒子和多奇异粒子的产生可以用来研究重离子碰撞中的初始瞬态场涨落。我们强调了在这些碰撞中所起的作用,结反结(JJbar)回路和强色电场(SCF)。本文在HIJING/BBbar v2.0模型的框架下,讨论了核子-核子质心能量为5.5TeV的中心(0-5%)Pb+Pb碰撞中SCF对重子产生的瞬态场涨落,特别是核修正因子R_AA从RHIC到LHC能量的预测演化。我们的研究结果表明,一个很好的描述基线基本p+p碰撞在这个能量的重要性。

英文摘要:

Strangeness and multi-strangeness particles production can be used to explore the initial transient field fluctuations in heavy ion collisions. We emphasize the role played by Junction anti-Junction (JJbar) loops and strong color electric fields (SCF) in these collisions. Transient field fluctuations of SCF on the baryon production in central (0-5%) Pb+Pb collisions at nucleon-nucleon centre of mass energy of 5.5 TeV will be discussed in the framework of HIJING/BBbar v2.0 model, looking in particular to the predicted evolution of nuclear modification factors R_AA from RHIC to LHC energies. Our results indicate the importance of a good description of the baseline elementary p+p collisions at this energy.
