利用Hijing事例generator研究核-核碰撞中的高p $_{t}$事例

Investigation of high p$_{t}$ events in Nucleus-Nucleus collisions using the Hijing event generator

Natasha Sharma, Madan M. Aggarwal

摘要:

近年来,RHIC能区的核-核碰撞引起了人们极大的兴趣,这是与高$p_{t}$物理\cite{ref1}有关的现象。高$p_{t}$粒子的抑制和背靠背喷流的消失与二元核子-核子碰撞的数量的缩放相比,表明在这些碰撞中产生了一个近乎完美的液体。利用高$p_{t}$对应的强子多重数和由北京事例发生器得到的核-核碰撞\cite{ref2}的无偏事例,给出了高$p_{t}$事例的自遮蔽结果.

英文摘要:

In recent years lot of interest has been observed in the nucleus-nucleus collisions at RHIC energies in phenomena related to high $p_{t}$ physics \cite{ref1}. The suppression of high $p_{t}$ particles and disappearance of back-to-back jets compared to the scaling with number of binary nucleon-nucleon collisions indicates that a nearly perfect liquid is produced in these collisions. Results on self shadowing of high $p_{t}$ events are presented using hadron multiplicity associated to high $p_{t}$ and unbiased events in nucleus-nucleus collisions \cite{ref2} obtained from the hijing event generator.
