摘要:

本文将单次散射中胶子辐射的Gunion Bertsch计算推广到有限质量夸克的情形。这种情况适用于中能重夸克在夸克-胶子等离子体中传播的辐射能量损失。我们更具体地讨论了死锥效应以及碰撞和辐射能量损失的质量层次,并提供了一些预测的观测值敏感的质量层次的能量损失在超相对论重离子碰撞。

英文摘要:

We extend the Gunion Bertsch calculation of gluon radiation in single scattering to the case of finite mass quarks. This case applies to the radiative energy-loss of heavy quarks of intermediate energies propagating in a quark gluon plasma. We discuss more specifically the dead cone effect as well as the mass hierarchy of the collisional and radiative energy loss and provide some predictions for observables sensitive to the mass hierarchy of energy loss in ultrarelativistic heavy ion collisions.
