重离子碰撞中黑洞形成的多重数

Multiplicities from black-hole formation in heavy-ion collisions

Elias Kiritsis, Anastasios Taliotis

摘要:

研究了共形和非共形背景中激波迎头碰撞中捕获面的形成。背景包括所有可能与QCD有关的有趣的限制和非限制背景。几个横向配置文件的冲击进行了调查,包括作为权力或指数下降的分布。不同的方式切断紫外线的贡献(预计在QCD微扰)进行了探讨。在一些合理的简化假设下,我们的估计被转换为RHIC和LHC上重离子碰撞的多重数的预测。

英文摘要:

The formation of trapped surfaces in the head-on collision of shock waves in conformal and non-conformal backgrounds is investigated. The backgrounds in- clude all interesting confining and non-confining backgrounds that may be relevant for QCD. Several transverse profiles of the shocks are investigated including distributions that fall-off as powers or exponentials. Different ways of cutting-off the UV contributions (that are expected to be perturbative in QCD) are explored. Under some plausible simplifying assumptions our estimates are converted into predictions for multiplicities for heavy-ion collisions at RHIC and LHC.
