| dc.description | This work presents a new phenomenological description of QCD vacuum where the color background field is depicted by a constant parallel vector with amplitude proportional to $σ\sim 0.28 GeV^2$. The familiar Regge relation can be derived directly in a classic meaning. A new mass formula of hadrons are conjectured to give a very consistent description of hadron mass spectra. The lower bounds of the baryon mass are determined to be $\sqrt{3σ}$ for nucleon and $\sqrt{5σ}$ for isospin-3/2 baryon. In the meanwhile, the mass-square differences of $1 {}^3 S_1$ and $1 {}^1 S_0$ meson states are obtained to be $2 σ$. We also predict the mass of the lowest four-quark state to be $\sqrt{4σ}$, which favors the $a_0(980)$ and $f_0(980)$ to be four-quark candidates. On the other hand, the effective heavy quark confinement potential is a direct result of this model. | |
