Confining modeling of quark propagator
Abstract A confining extension of the quark model with nonlocal currents is proposed. The quark propagator is modified by introducing a cut in $$\alpha $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>α</mml:mi> </mml:math> -space, which in momentum space corresponds to the subtraction of pole singularities. A two-phase structure is proposed for modeling the confinement-deconfinement phase transition. In the confined phase, the quark propagator does not have any pole singularities, while in the deconfined phase, there is a single quark pole.
