Abstract
We consider backreaction by nonsupersymmetric D7/antiD7 probe branes in the KupersteinSonnenschein model at finite temperature Using the smearing technique we obtain an analytical solution for the backreacted background to leading order in N f /N c This backreaction explicitly breaks the conformal invariance and introduces a dimension 6 operator in the dual field theory which is an irrelevant deformation of the original conformal field theory We further probe this backreacted background by introducing an additional set of probe brane/antibrane This additional probe sector undergoes a chiral phase transition at finite temperature which is absent when the backreaction vanishes We investigate the corresponding phase diagram and the thermodynamics associated with this phase transition We also argue that additional probes do not suffer from any instability caused by the backreaction which suggests that this system is stable beyond the probe limit
