在QCD耦合常数S中，计算了强磁场B中重夸克的动量扩散系数k和？分别沿平行和垂直于B的方向，并考虑了与相对论重离子碰撞有关的一个区域Seb T2 EB，使得轻夸克的热激发被限制在最低的朗道能级(Lll)态.在消失的轻夸克质量极限中，我们发现
We compute the momentum diusion coecients of heavy quarks, k and ?, in a strong magnetic eld B along the directions parallel and perpendicular to B, respectively, at the leading order in QCD coupling constant s. We consider a regime relevant for the relativistic heavy ion collisions, seB T 2 eB, so that thermal excitations of light quarks are restricted to the lowest Landau level (LLL) states. In the vanishing light-quark mass limit, we nd
