abstract
We prove that Nambu-Jona-Lasinio model is an exact description of infrared QCD deriving it from QCD Lagrangian. The model we obtain is renormalizable and confining but, taking very small momenta fixes completely all the parameters of the Nambu-Jona-Lasinio model through those of QCD. The choice of the infrared propagator is done consistently with recent numerical results from lattice and Dyson-Schwinger equations for Yang-Mills theory. The model we get coincides, once the ultraviolet contribution is removed, with the one proposed by Langfeld, Kettner and Reinhardt [Nucl. Phys. A {\bf 608}, 331 (1996)].

Quintessence Dark Energy from non-perturbative Higgs-Yang-Mills mass gap
A strongly coupled Higgs-Yang-Mills dark sector with a cosmic-triad gauge field can mimic quintessence dark energy with an equation of state approaching -1, provided the solution phase is tuned.
