论文摘要
我们使用时间依赖的轻阵汉密尔顿方法研究了夸克射流在高能重核上的散射。我们模拟了相对论核的强大颜色场中夸克的实时演变，称为彩色玻璃冷凝物。我们通过让夸克射流带有逼真的有限纵向动量来研究亚欧基效应，并发现夸克的横向坐标分布发生了很大的变化。我们还通过$ \ ket {q}+\ ket {qg} $ fock Space中的Gluon排放来观察夸克的能量损失。这种方法为我们提供了从非扰动方面研究散射过程的机会。
We investigate the scattering of a quark jet on a high-energy heavy nucleus using the time-dependent light-front Hamiltonian approach. We simulate a real-time evolution of the quark in a strong classical color field of the relativistic nucleus, described as the Color Glass Condensate. We study the sub-eikonal effect by letting the quark jet carry realistic finite longitudinal momenta, and we find sizeable changes on the transverse coordinate distribution of the quark. We also observe the energy loss of the quark through gluon emissions in the $\ket{q}+\ket{qg}$ Fock space. This approach provides us with an opportunity to study scattering processes from non-perturbative aspects.
