论文摘要
我们用玻尔兹曼扩散方程和在线性玻尔兹曼传输（LBT）模型中重型离子碰撞中的喷射繁殖的完整模拟说明，触发垂直于传播方向的飞机传输系数的空间梯度可以导致逆向动量分布中的漂移和不对称。这种不对称性取决于沿横向梯度和传播长度的空间位置。它可以用来定位初始喷气生产位置，以进行重型离子碰撞中夸克 - 杜伦等离子体的喷射淬火和特性的更详细的研究。
We illustrate with both a Boltzmann diffusion equation and full simulations of jet propagation in heavy-ion collisions within the Linear Boltzmann Transport (LBT) model that the spatial gradient of the jet transport coefficient perpendicular to the propagation direction can lead to a drift and asymmetry in the transverse momentum distribution. Such an asymmetry depends on both the spatial position along the transverse gradience and the propagating length. It can be used to localize the initial jet production positions for more detailed studies of jet quenching and properties of the quark-gluon plasma in heavy-ion collisions.
