标题： QCD-Motivated Pomeron and High Energy Hadronic Diffractive Cross Sections

摘要： 软衍射截面在 $pp$ (或 $\bar pp$)， $\pi p$ 和 $\gamma p$ 碰撞中通过 QCD 驱动的 pomeron 进行计算。 幅度的 $s$-通道单位化通过 eikonal 方法进行，在强子的夸克结构框架下考虑了颜色屏蔽。 对衍射过程的描述得到了裸 pomeron $P$的参数，这些参数被发现与 Lipatov 的 pomeron 的相应参数接近。 裸 pomeron 的参数以及三个 reggeon 块$PGG$($G$是一个 reggeized 胶子) 的参数已由中等高能的数据确定；对于超高能，做出了预测。 裸 pomeron 的截距与深度非弹性散射的低$x$数据有显著的一致性。 进行了有效颜色透明半径的评估，该半径可用于强子-核反应中。 显示英文摘要

摘要： Soft diffractive cross sections in $pp$ (or $\bar pp$), $\pi p$ and $\gamma p$ collisions are calculated using QCD-motivated pomeron. The $s$-channel unitarization of the amplitude is performed by the eikonal approach, and in the framework of the quark structure of hadrons the colour screening is taken into account. The performed description of the diffractive processes has led to the parameters of the bare pomeron $P$ which occurred to be close to the corresponding parameters of the Lipatov's pomeron. Parameters of the bare pomeron and those of the three-reggeon block $PGG$ ($G$ is a reggeized gluon) has been fixed by the data at moderately high energies; for superhigh energies the predictions are made. The intercept of the bare pomeron is found to be in remarkable agreement with the low-$x$ data for deep inelastic scattering. An evaluation of the effective colour transparency radius is done which can be used in hadron-nuclei reactions.
