标题： Non-perturbative collisional energy loss of heavy quarks in quark-gluon plasma

摘要： 我们提出了一种快重夸克在夸克胶子等离子体中能量损失的新机制。 该机制基于由强拓扑涨落的胶子场（由瞬子表示）引起的异常色磁夸克胶子介子相互作用导致的介子产生。 我们发现，这种机制对夸克胶子等离子体中重夸克的碰撞能量损失有显著贡献，这表明非微扰现象在强相互作用的夸克胶子等离子体中起着非平凡的作用。 显示英文摘要

摘要： We suggest a new mechanism for the energy loss of fast heavy quarks in quark-gluon plasma. This mechanism is based on pion production caused by the anomalous chromomagnetic quark-gluon-pion interaction induced by strong topological fluctuations of the gluon fields represented by instantons. We found that this mechanism gives a considerable contribution to the collisional energy loss of a heavy quark in quark-gluon plasma, which shows a nontrivial role of nonperturbative phenomena in strongly interacting quark-gluon plasma.
