核内多次散射引起的喷流能量损失

Jet energy loss due to multiple scattering in the nucleus

M. A. Braun

摘要:

在红外截止的微扰QCD框架下研究了核靶中多次碰撞引起的喷注能量损失。它的计算迭代程序的开发,它允许可靠地找到多达16个连续的碰撞再散射。在5-10 GeV/c的范围内,计算出的标度变量的位移在中等$x$和横向动量$p$处达到0.1量级的值。发现这种位移与靶的原子序数和能量无关。

英文摘要:

Energy loss of a jet due to multiple collisions in the nuclear target is studied in the framework of the perturbative QCD with an infrared cutoff. An iterational procedure for its calculation is developed, which allows to reliably find up to 16 successive collisions in rescattering. The calculated shift of the scaling variable reaches values of the order 0.1 at medium $x$ and transverse momentum $p$ in the interval 5-10 GeV/c. The shift is found to be independent of the atomic number of the target and energy.
