论文摘要
我们提出了基于扰动QCD的真空和中置强国的模型。诱导的能量损失和核吸收的影响已包括在内。主要目的是确定这些机制对可观察到的多样性比的相对贡献，该比率可在半包含的深弹性散射中测量氘和核靶标。这与确定生产长度$ LP $的确定直接相关，这对于夸克变成前座头所必需的。我们将结果与爱马仕的数据进行比较，以达到多重比和$ p_t $ -BROADENING，并证明整个数据集的描述（保持模型参数固定）对$ LP $构成了强大的限制。与诱导能量损坏的模型相反，我们发现爱马仕能量的核吸收产生了重要的贡献。最后，我们讨论了研究LHC物理学的一些后果，并为未来的EIC实验提供了模型预测。
We present a perturbative QCD based model for vacuum and in-medium hadronization. The effects of induced energy loss and nuclear absorption have been included. The main objective is the determination of the relative contribution of these mechanisms to the multiplicity ratio observable, measured in semi-inclusive deep-inelastic scattering off deuterium and nuclear targets. This is directly related to the determination of the production length, $Lp$, necessary for a quark to turn into a prehadron. We compare our results with HERMES data for multiplicity ratio and $p_t$-broadening, and show that the description of the whole data set, keeping the model parameters fixed, puts strong constrains on $Lp$. Contrary to induced-energy-loss based models, we find an important contribution from nuclear absorption at HERMES energies. Finally, we discuss some consequences of our study for the LHC physics, and we present the model predictions for the future EIC experiment.
