Query: QCD chiral symmetry restoration with a large number of quarks in a model
  with a confining propagator and dynamically massive gluons   Considering a QCD chiral symmetry breaking model where the gap equation
contains an effective confining propagator and a dressed gluon propagator with
a dynamically generated mass, we verify that the chiral symmetry is restored
for a large number of quarks $n_{f}\approx 7-13$. We discuss the uncertainty in
the results, that is related to the determination of the string tension
($K_{F}$), appearing in the confining propagator, and the effective gluon mass
($m_{g}$) at large $n_{f}$.
