在大型强子对撞机的中心铅铅碰撞中，预计喷流率在喷流可以在基础事件的背景下完全重建的能量下会很高。这将打开量化的影响，部分子能量损失的可能性，通过介质诱导胶子辐射，喷流淬火，通过详细测量的修改确定的喷流的纵向和横向结构。我们将提出的Monte Carlo模拟强烈表明，为了获得探针敏感的QCD介质的属性，它是强制性的，以测量高p T部分子碎片与低p T粒子从辐射胶子。因此，ALICE在100 MeV-100 GeV范围内Δp/p < 10%的出色带电粒子跟踪能力与拟议的ALICE电磁量热计EMCAL相结合，代表了LHC喷流猝灭研究的理想工具。
In central Pb-Pb collisions at the LHC, jet rates are expected to be high at energies at which jets can be fully reconstructed over the background of the underlying event. This will open the possibility of quantifying the effect of partonic energy loss through medium induced gluon radiation, jet quenching, by detailed measurement of the modification of the longitudinal and transverse structure of identified jets. We will present Monte Carlo simulations strongly indicating that, in order to obtain probes sensitive to the properties of the QCD medium, it is mandatory to measure the high-p T parton fragments together with the low-p T particles from the radiated gluons. Hence, the excellent charged particle tracking capabilities of ALICE with Δp/p < 10% from 100 MeV-100 GeV combined with the proposed electromagnetic calorimeter for ALICE, EMCAL, represent an ideal tool for jet quenching studies at the LHC.
