夸克-胶子等离子体中的辐射过程

Radiative Processes in Quark-Gluon Plasma

Trambak Bhattacharyya, Surasree Mazumder, Jan-e Alam

摘要:

通过放松一些在早期工作中使用的近似,从过程$\mathrm{gg\rightarrow ggg}$发射胶子的光谱进行了评估。本文所得到的公式已应用于几个物理量。导出了虚部分子辐射胶子死锥的一般表达式。我们观察到,与传统的重夸克死锥相比,高虚性引起的抑制是巨大的。

英文摘要:

The spectrum of emitted gluons from the process $\mathrm{gg\rightarrow ggg}$ has been evaluated by relaxing some of the approximations used in earlier works. The formula obtained in the present work has been applied to several physical quantities. A general expression for the dead cone of gluons radiated by virtual partons has been derived. It is observed that the suppression caused by the high virtuality is overwhelmingly large as compared to that on account of conventional dead-cone of heavy quarks.
