Induced gluon radiation and energy loss of heavy quark in hot and dense QCD media are discussed. Using the light-cone path integral approach, an analytical formula of the energy loss of heavy quark is derived. The results show that the quark energy loss obviously depends on the mass of quark, i. e. a remarkable suppression occurs in the case of heavy quark comparing to a light one. The radiative energy loss of energetic quark is proportional to L 2, where L is the length of the medium. The dependence of...

在热、稠密的 QCDmedia 的重夸克的导致的 gluon 放射和精力损失被讨论。用轻锥的路径积分途径，重夸克的精力损失的一个分析公式被导出。结果证明夸克精力损失显然取决于夸克的团， i.e.a 显著抑制发生在比作发光的重夸克的箱子中。精力充沛的夸克的放射的精力损失与 L~2 成正比，在 L 是媒介的长度的地方。L~2 上的精力损失的依赖与减少的夸克精力转到 L。
