Color Diagrams for Non Vacuum Reggeons in Hadron-Hadron Interactions

TL;DR

This paper explores the relationship between dual resonance models and QCD color diagrams in hadron-hadron interactions, revealing differences in diagram structures and implications for baryon production in high-energy collisions.

Contribution

It establishes a correspondence between dual diagrams and QCD color diagrams for non-vacuum exchanges, and introduces a new color diagram for proton-proton interactions based on the principle of conformity.

Findings

Dual diagrams with quark-antiquark states exist in certain channels.

A new color diagram for pp interactions was proposed.

The model predicts increased baryon chemical potential in nucleus-nucleus collisions.

Abstract

One-to-one correspondence between dual diagrams of dual resonance model and QCD based color diagrams describing non vacuum exchanges in pi+ pi-, pi+- p, p anti p interactions is discussed. Both for dual and color diagrams there are state with quark-antiquark in t channel and state, in which only coherent quark string exists, in s channel. There are no such dual diagrams in pp interaction. Color diagram for pp interaction was found basing on principle of conformity. Secondary hadrons spectrum, obtained from this diagram, has nucleon in its central region. This effect may lead to increase of baryon chemical potential in nucleus-nucleus collisions in facilities NICA and FAIR.
