论文摘要
使用颜色偶极式形式主义并考虑到饱和效应，研究了高能量的$ EP $碰撞中的领先中子（LN）生产。我们更新了吸收效应的处理，并估算了这些影响对运动范围内LN光谱的影响，该运动范围将由电子离子对撞机（EIC）和大型强子电子撞机（LHEC）探测。我们证明，Feynman缩放与饱和相关的缩放不是因吸收效应而违反。此外，我们的结果表明，在小光子虚拟上，LN光谱受到强烈抑制。这些结果表明，在未来的$γπ$横截面的测量中，无法从领先的中子产生数据中提取吸收作用。
Leading neutron (LN) production in $ep$ collisions at high energies is investigated using the color dipole formalism and taking into account saturation effects. We update the treatment of absorptive effects and estimate the impact of these effects on LN spectra in the kinematical range that will be probed by the Electron Ion Collider (EIC) and by the Large Hadron electron Collider (LHeC). We demonstrate that Feynman scaling, associated to saturation, is not violated by the inclusion of absorptive effects. Moreover, our results indicate that the LN spectrum is strongly suppressed at small photon virtualities. These results suggest that absorptive effects cannot be disregarded in future measurements of the $γπ$ cross section to be extracted from data on leading neutron production.
