在最低朗道近似下，计算了强外磁场作用下夸克-胶子等离子体中重夸克动量扩散系数。特别是，我们应用硬热回路（HTL）技术的有效胶子传播，广义的热和磁化介质。利用导出的有效HTL胶子传播子和LLL夸克传播子，我们解析地导出了超出静态极限的粲夸克和底夸克的纵向和横向动量扩散系数的全部结果。我们还显示了这些系数在两种特殊情况下，重夸克是平行或垂直于磁场移动的数值结果。
We present a calculation of the heavy quark momentum diffusion coefficients in a quark-gluon plasma under the presence of a strong external magnetic field, within the lowest Landau level (LLL) approximation. In particular, we apply the hard thermal loop (HTL) technique for the resummed effective gluon propagator, generalized for a hot and magnetized medium. Using the derived effective HTL gluon propagator and the LLL quark propagator we analytically derive the full results for the longitudinal and transverse momentum diffusion coefficients for charm and bottom quarks beyond the static limit. We also show numerical results for these coefficients in two special cases where the heavy quark is moving either parallel or perpendicular to the magnetic field.
