稠密QCD介质中初、终态辐射的相干效应

Coherence effects between the initial and final state radiation in a dense QCD medium

Mauricio Martinez

摘要:

在这些会议的贡献,我们回顾了我们最近的结果,介质修改的初始和最终状态之间的辐射的相干模式。我们研究了高能部分子在经历硬散射后穿过有限大小的致密QCD介质时的单胶子产生。多个散射导致不同发射器之间的干扰的部分抑制,这为大角度发射打开了相空间。我们简要地讨论了广义的这种设置来描述胶子生产的情况下,PA碰撞,包括有限的长度和能量的修正。这里研究的配置可能有现象学的后果,在高能核碰撞。

英文摘要:

In these proceedings contribution we review our recent results of medium modifications to the coherence pattern between the initial and final state radiation. We study single gluon production off a highly energetic parton that undergoes a hard scattering and subsequently crosses a dense QCD medium of finite size. Multiple scatterings lead to a partial suppression of the interferences between different emitters that opens the phase space for large angle emissions. We briefly discuss the generalization of this setup to describe gluon production in the case of pA collisions by including finite length and energy corrections. The configuration studied here may have phenomenological consequences in high-energy nuclear collisions.
