# Particle states of Lattice QCD

## TL;DR

This paper investigates the particle states in Lattice QCD, analyzing how the number of states and their masses evolve with temperature, revealing a transition from hadronic to quark-gluon plasma characteristics.

## Contribution

It provides a detailed analysis of the degeneracy factors and average masses of particles in Lattice QCD across different temperatures, highlighting the transition region.

## Key findings

- Number of states converges to ideal Quark-Gluon values above 230 MeV.
- Masses of particles remain high even at high temperatures.
- Steep decrease in states and mass between 150-160 MeV indicates hadronic nature.

## Abstract

We determine the degeneracy factor and the average particle mass of particles that produce the Lattice QCD pressure and specific entropy at zero baryon chemical potential. The number of states of the gluons and the quarks are found to converge above $T=$230 MeV to almost constant values, close to the number of states of an ideal Quark-Gluon Phase, while their assigned masses retain high values. The number of states and the average mass of a system containing quarks in interaction with gluons are found to decrease steeply with increase of temperature between $T \sim 150$ and 160 MeV, a region contained within the region of the chiral transition. The minimum value of the number of states within this temperature interval indicates that the states are of hadronic nature.
