标题： Propagation of QCD Color through Strongly Interacting Systems

摘要： 通过使用半包容深度非弹性散射的几何模型，研究了QCD色在原子核中的传播。 实验数据之前由HERMES合作组发表，包括多重性比可观测量（2007）和横向动量展宽可观测量（2010）。 我们对这两个可观测量进行同时拟合，以估计（1）夸克的颜色寿命，（2）夸克能量损失，（3）$\hat{q}$输运系数，以及（4）与介质的强子相互作用截面。 我们给出了此拟合的初步结果。 显示英文摘要

摘要： The propagation of QCD color through atomic nuclei is studied via a new analysis using a geometric model of semi-inclusive deep inelastic scattering. The experimental data were previously published by the HERMES Collaboration and consisted of the multiplicity ratio observable (2007) and the transverse momentum broadening observable (2010). We perform a simultaneous fit of these two observables to estimate (1) the color lifetime of the quark, (2) quark energy loss, (3) the $\hat{q}$ transport coefficient, and (4) the cross section for hadronic interaction with the medium. We present preliminary results for this fit.
