核碰撞中喷流的理论和唯象

The theory and phenomenology of jets in nuclear collisions

Ivan Vitev, Ben-Wei Zhang, Simon Wicks

摘要:

我们回顾了最近在大型强子对撞机arXiv:0810.2807 [hep-ph]上对重核超相对论反应中喷流形状和喷流截面的深入研究的结果。我们证明,在最高的对撞机能量,这些可观的成为可行的作为一个新的,差分和准确的测试的基础QCD理论。我们的方法允许详细的模拟实验接受/切割,帮助隔离射流出现从密集的QGP。我们第一次表明,受激胶子发射的模式可以与可变淬火的喷流率,并提供了一个近似模型无关的方法来确定介质诱导韧致辐射谱的特性。阐明了这种截面衰减与介质内射流形状之间的联系。

英文摘要:

We review selected results from a recent in-depth study of jet shapes and jet cross sections in ultra-relativistic reactions with heavy nuclei at the LHC arXiv:0810.2807 [hep-ph]. We demonstrate that at the highest collider energies these observables become feasible as a new, differential and accurate test of the underlying QCD theory. Our approach allows for detailed simulations of the experimental acceptance/cuts that help isolate jets emerging from a dense QGP. We show for the first time that the pattern of stimulated gluon emission can be correlated with a variable quenching of the jet rates and provide an approximately model-independent approach to determining the characteristics of the medium-induced bremsstrahlung spectrum. The connection between such cross section attenuation and the in-medium jet shapes is elucidated.
