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

## TL;DR

This paper models rapidity gaps in double diffraction events at LHC using a topological string junction framework, predicting discrete gap structures and potential metastable states related to pomeron torus configurations.

## Contribution

It introduces a novel topological model of pomeron exchange involving string junctions and torus diagrams to explain rapidity gap phenomena in high-energy proton-proton collisions.

## Key findings

- Discrete structure in gap distribution at large rapidities.
- Approximately 1.2% of inclusive events exhibit rapidity gaps or doubled multiplicity.
- Pomeron torus and hexagon configurations influence gap dynamics and metastable states.

## Abstract

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.
