Studying color connection effects of $e^+e^- \to c\bar{c}c\bar{c} \to \Xi_{cc}+X $ process within Quark Combination Model

TL;DR

This paper investigates the color connection effects in a specific four-heavy-quark system produced in electron-positron annihilation, comparing hadronization models to understand their influence on baryon and tetraquark production.

Contribution

It revisits the color connection in four-heavy-quark systems and compares hadronization effects using the Quark Combination Model and Lund String Model.

Findings

Color connection effects are consistent across different hadronization models.

Hadronization models have limited impact on global properties related to color connection.

The study enhances understanding of doubly heavy baryon and tetraquark production mechanisms.

Abstract

The color connection of the parton system is an important bridge to connect the perturbative process and the hadronization one. The special color connection of four-heavy-quark system in $e^+e^-$ annihilation, which is the necessary one for the doubly heavy baryon and tetraquark productions is revisited. The hadronization effects, investigated with the help of the Quark Combination Model are compared with the corresponding results employing the Lund String Model in our previous work. The global properties related to a certain color connection are not sensitive to various hadronization models.
