论文摘要
在全息方法中研究了各向异性热致密QGP的能量损失。通过使用有效的潜在技术估算空间威尔逊环路的行为来计算能量损失。我们研究了在完全各向异性背景下有效潜力对空间威尔逊环方向的依赖性。为此，我们获得了一般公式，以实现有效电势壁的有效潜在和研究外观。我们考虑了由爱因斯坦 - 迪拉特（Einstein-Dilaton） - 三位 - 马克斯韦（Maxwell）支持的特定完全各向异性模型[ARXIV：2011.07023]。有效的潜在强烈取决于各向异性和磁场的参数，因此能量损失取决于物理参数$ - $ $ $ t $，$μ$，$ C_B $和方向。方向取决于移动的重夸克速度，重离子碰撞及其冲击参数向量之间的角度。
Energy loss in anisotropic hot dense QGP in external magnetic field is studied within holographic approach. Energy loss is calculated by estimation of behaviour of the spatial Wilson loops using the effective potential technique. We examine the dependence of the effective potential on the spatial Wilson loops orientation in fully anisotropic background. For this purpose we obtain general formulas for the effective potential and study appearance of the effective potential dynamical wall. We consider particular fully anisotropic model [arXiv:2011.07023] supported by Einstein-Dilaton-three-Maxwell action. The effective potential strongly depends on the parameters of anisotropy and magnetic field, therefore the energy loss depends on physical parameters $-$ $T$, $μ$, $c_B$ and orientation. Orientation is determined by angles between the moving heavy quark velocity, the axis of heavy ions collision and their impact parameter vector.
