  Many recent works on large N holographic QCD in the planar limit have not
considered UV completions, restricting exclusively towards analyzing the IR
physics. Due to this, the UV problems like Landau poles and divergences of
Wilson loops including instabilities at high temperatures have not been
addressed. In some of our recent papers, we have discussed a possible UV
completion, which is conformal in the UV and confining in the far IR, that
avoids the Landau poles and the Wilson loop divergences. In this paper we give
a field theory realization of this including the complete RG flow. We extend
our UV complete model to study scenarios both above and below the deconfinement
temperature and argue how phase transition in our model should be understood.
Interestingly, because of the UV completion, subtle issues like instability due
to negative specific heat do not appear. We also briefly elucidate the
advantages that our model may have over other models studying large N thermal
QCD.
