TY - JOUR AU - Vento, V. PY - 2013 DA - 2013// TI - Confinement, the gluon propagator and the interquark potential for heavy mesons T2 - Eur. Phys. J. A JO - European Physical Journal A SP - 71 EP - 7pp VL - 49 IS - 6 PB - Springer AB - The interquark static potential for heavy mesons described by a massive one-gluon exchange interaction obtained from the propagator of the truncated Dyson-Schwinger equations does not reproduced the expected Cornell potential. I show that no formulation based on a finite propagator will lead to confinement of quenched QCD. I propose a mechanism based on a singular nonperturbative coupling constant which has the virtue of giving rise to a finite gluon propagator and (almost) linear confinement. The mechanism can be slightly modified to produce the screened potentials of unquenched QCD.
