摘要：

In this work, the distance between a quark-antiquark pair is analyzed through both the confinement potential and the hadronic total cross-section. Using the Helmholtz free energy, the entropy is calculated near the minimum of the total cross-section through the confinement potential. A fitting procedure for the proton-proton total cross-section is carried out, defining the fit parameters. Therefore, the only remaining free parameter in the model is the mass-scale.. used to define the running coupling constant of the light-front the approach to QCD. The mass scale controls the distance.. between the quark-antiquark pair and, under some conditions, allows the appearance of free quarks even within the confinement regime of QCD.
