| dc.description | We extend previous work on the IR regime approximation of QCD in which the dominant contribution comes from a dressed two-gluon effective metric-like field $G_{μν} = g_{ab} B^{a}_μ B^{b}_ν$ ($g_{ab}$ a color SU(3) metric). The ensuring effective theory is represented by a pseudo-diffeomorphisms gauge theory. The second -quantized $G_{μν}$ field, together with the Lorentz generators close on the $\bar{SL}(4,R)$ algebra. This algebra represents a spectrum generating algebra for the set of hadron states of a given flavor - hadronic "manifields" transforming w.r.t. $\bar{SL}(4,R)$ (infinite-dimensional) unitary irreducible representations. The equations of motion for the effective pseudo-gravity are derived from a quadratic action describing Riemannian pseudo-gravity in the presence of shear ($\bar{SL}(4,R)$ covariant) hadronic matter currents. These equations yield $p^{-4}$ propagators, i.e. a linearly rising confining potential $H(r) \sim r$, as well as linear $J \sim m^{2}$ Regge trajectories. The $\bar{SL}(4,R)$ symmetry based dynamical theory for the QCD IR region is applied to hadron resonances. All presently known meson and baryon resonances are successfully accommodated and various missing states predicted.
