high-pT强子的猝灭:另一种方案

Quenching of high-pT hadrons: Alternative scenario

B. Z. Kopeliovich, I. K. Potashnikova, Ivan Schmidt

摘要:

提出了一种新的方案,替代能量损失,在RHIC观察到的高pT强子的抑制。在核碰撞产生的稠密介质的极限下,产生(前)强子的平均自由程为零,核抑制R_{AA}完全受产生长度的控制。对RHIC实验数据进行了无参数解释,并给出了LHC的预言。

英文摘要:

A new scenario, alternative to energy loss, for the observed suppression of high-pT hadrons observed at RHIC is proposed. In the limit of a very dense medium crated in nuclear collisions the mean free-path of the produced (pre)hadron vanishes, and and the nuclear suppression, R_{AA} is completely controlled by the production length. The RHIC data are well explained in a parameter free way, and predictions for LHC are provided.
