论文摘要
我们研究了辐射过程对$ p _ {\ perp} $的贡献 - 在扩展的夸克 - 葡萄糖等离子体中扩大了快速部分。结果表明，针对$ \ langle p _ {\ perp}^2 \ rangle $的辐射校正用于RHIC和LHC中$ aa $ - collisisions生产的QGP $，并且与非放射性贡献的绝对值相当。我们发现，与静态介质相比，QGP扩展可以增强$ p_ \ perp $ - 宽带的辐射抑制。
We study contribution of radiative processes to $p_{\perp}$-broadening of fast partons in an expanding quark-gluon plasma. It is shown that the radiative correction to $\langle p_{\perp}^2\rangle$ for the QGP produced in $AA$-collisions at RHIC and LHC may be negative, and comparable in absolute value with the non-radiative contribution. We have found that the QGP expansion enhances the radiative suppression of $p_\perp$-broadening as compared to the static medium.
