摘要:

我们目前的结果和预测,在下一个领先的顺序,最近的大型强子对撞机铅铅运行的质量中心的能量为2.76 TeV每核子核子对。具体来说,我们专注于抑制单,双包容性射流截面,并演示如何双射流不对称,最近测量的ATLAS和CMS,可以从这个一般的结果。由电弱玻色子标记的喷流的例子是$Z^0$ +喷流通道。我们预测的签名过渡从增强到抑制的标记射流有关的介质引起的修改的部分子淋浴。最后,我们以最近ALICE带电强子衰减数据为例,阐明了包容喷注、标记喷注和双喷注的抑制与包容粒子的猝灭之间的关系。

英文摘要:

We present results and predictions at next-to-leading order for the recent LHC lead-lead run at a center-of-mass energy of 2.76 TeV per nucleon-nucleon pair. Specifically, we focus on the suppression the single and double inclusive jet cross sections and demonstrate how the di-jet asymmetry, recently measured by ATLAS and CMS, can be extracted from this general result. The case of jets tagged by an electroweak boson is exemplified by the $Z^0$+jet channel. We predict a signature transition from enhancement to suppression of the tagged jet related to the medium-induced modification of the parton shower. Finally, we clarify the relation between the suppression of inclusive jets, tagged jets and di-jets and the quenching of inclusive particles on the example of the recent ALICE charged hadron attenuation data.
