We demonstrate analytically that a linear rising potential between massive quarks is generated by infrared singularities in the dressed quark-gluon vertex. The self consistent mechanism that generates these singularities is driven by the scalar Dirac amplitudes of the full vertex and the quark propagator. These can only be present when chiral symmetry is broken. We have thus uncovered a novel mechanism that directly links chiral symmetry breaking with confinement.engjournal articlehttp://dx.doi.org/10.1142/S021773230802700Xhttp://arxiv.org/abs/hep-ph/0607293http://www.worldscientific.comopen access53Dyson-Schwinger EquationsYang-Mills TheoryGauge-TheoriesInfrared BehaviorQcdLimitFísica (Física)22 Física
