  The Nambu Jona-Lasinio model of chiral symmetry breaking predicts a second
order chiral phase transition. If the fermions in addition have non-abelian
gauge interactions then the transition is expected to become a crossover as the
NJL term enhances the IR chiral symmetry breaking of the gauge theory. We study
this behaviour in the holographic Dynamic AdS/QCD description of a non-abelian
gauge theory with the NJL interaction included using Witten's multi-trace
prescription. We study the behaviour of the mesonic spectrum as a function of
the NJL coupling and the ratio of the UV cut off scale to the dynamical scale
of the gauge theory.
