Query: Flavor corrections to the entanglement entropy   We consider the holographic entanglement entropy in N=4 SYM coupled to
massive flavor degrees of freedom. The flavors are introduced by putting D7
branes in AdS_5. The resulting geometry including the backreaction of the
branes is known in a perturbation expansion in the ratio N_f/N_c. We consider
the expansion to first order, and compute the entanglement entropy of a region
of the boundary. We consider two different cases for the geometry of the
region: a slab and a ball. We find analytic solutions for the minimal surfaces
in the bulk whose area gives the entropy, and analyze the structure of the UV
divergence and the dependence on the masses. Our results confirm the general
structure that was predicted by free field theory calculations, but with
coefficients that depend on the coupling.
