LHC和重子-反重子环面双衍射事例的快度间隙

Rapidity Gaps in Double Diffraction Events at LHC and Baryon-anti Baryon Torus

O. I. Piskounova

摘要:

在大型强子对撞机上测量到的正的重子-反重子产生不对称性是高能质子-质子相互作用中弦结动力学的真实证明。高能质子-质子碰撞中坡密子交换的拓扑表示是被夸克-胶子网覆盖的圆柱图。我假设双衍射过程可以表示为一个坡密子与两个坡密子柱的中心环交换的图,这类似于带柄的坡密子图或坡密子环面图。考虑到三个胶子结(SJ)的重子数为正,而反结的重子荷为负,我们的Pomeron结构只能由一定数量的由3个弦结和3个反结顶点构成的六边形所覆盖.我们有理由认为,DD中快度隙的动力学性质应该由坡密子环面表面的六边形数目决定。因此,DD事件的能隙分布在大能隙区域具有一定的离散结构。此外,弦结聚集体可以作为亚稳态粒子在DD相互作用后释放。在中心快度间隙中,存在另一个具有坡密子环组态的多粒子过程,它给出了一个多重数加倍的事件。它对应于沿着坡密子环的切口。具有DD中的间隙的事件以及具有加倍的多重性的事件各自在包含性产生截面的1.2%的水平上进行。

英文摘要:

The positive baryon-antibaryon production asymmetries that have been measured at LHC are real demonstrations of string junction dynamics in the proton-proton interactions of high energies. The topological presentation of pomeron exchange in the proton-proton collision of high energy is cylinder diagram that is covered with quark-gluon net. I assume that the process of double diffraction (DD) can be presented as a diagram of one pomeron exchange with the central loop of two pomeron cylinders, that is similar to the pomeron diagram with the handle or the pomeron torus. Taking into account that the junction of three gluons (SJ) has the positive baryon number, as well as the antijunction is of negative baryon charge, our pomeron construction can be covered by only a certain number of hexagons that are constructed of 3 string junction and 3 antijunction vertices each. It is reasonable to expect that the dynamics of rapidity gaps in DD should be determined by the number of hexagons on the surface of pomeron torus. Therefore, the gap distribution in DD events has some discrete structure in the region of large gaps. Moreover, the string-junction conglomerate could be released after DD interaction as a metastable particle. There is another multiparticle process with the pomeron loop configuration that gives an event with doubled multiplicity in the central rapidity gap. It corresponds to the cut along the pomeron loop. The events with the gap in DD as well as the events with doubled multiplicity, each go on the level of 1.2% of the inclusive production cross section.
