论文摘要
在这封信中,我们考虑了质子核和电磁(超脂质)机制在质子核核的相干衍射中的强度和电磁(超脂质)机制。我们明确说明了后者的主导地位,并在$ \ sqrt {s_ {nn}} = 8.16 $ tev中解释了$ ppb $ collisisions $ ppb $ collisions中的远期快速差距分布的CMS数据。特别是,我们提供了简单的估计,从而提供了Pomeron-Proton拓扑中$δη^f $分布的大小和形状的良好,半定量的描述。我们还对质子氧气运行做出了预测。
In this Letter, we consider strong and electromagnetic (ultraperipheral) mechanisms in proton-nucleus coherent diffraction at the CERN Large Hadron Collider. We explicitly demonstrate the dominance of the latter and explain the CMS data on the forward rapidity gap distribution in $pPb$ collisions at $\sqrt{s_{NN}}=8.16$ TeV. In particular, we provide simple estimates, which give a good, semi-quantitative description of both magnitude and shape of the $Δη^F$ distribution in the Pomeron-proton topology. We also make predictions for the proton-oxygen run.
