# Chromoelectric and chromomagnetic fields for the static gluon-quark-antiquark system

## TL;DR

This study uses lattice QCD to analyze the chromoelectric and chromomagnetic fields in a static gluon-quark-antiquark system, shedding light on hadron structure and confinement mechanisms.

## Contribution

It provides the first detailed lattice QCD analysis of flux tubes in gluon-quark-antiquark systems with different geometries, including hybrid states.

## Key findings

- Flux tubes of chromoelectric fields observed in different geometries.
- Differences between fundamental and adjoint flux tube models identified.
- Insights into the microscopic structure of hybrid hadrons gained.

## Abstract

The chromoelectric and chromomagnetic fields, created by a static gluon-quark-antiquark system, are computed in the quenched approximation of lattice QCD, in a $24^3\times 48$ lattice at $\beta=6.2$. We study two geometries, one with a U shape and another with an L shape. The degenerate case of the two gluon glueball is also studied. This is relevant to understand the microscopic structure of hadrons, in particular of hybrids. This also contributes to understand confinement with flux tubes of the chromoelectric field, and to discriminate between the models of fundamental or adjoint tubes.
