Query: Holographic entanglement entropy for massive flavours in dS_4   We examine the holographic entanglement entropy of spherical regions in de
Sitter space in the presence of massive flavour fields which are modelled by
probe D7 branes in AdS_5xS^5. We focus on the finite part of the massive
correction to the entropy in the limits of small mass and large mass that are
separated by a phase transition between two topologically distinct brane
embeddings. For small masses, it approaches the flat space result for small
spheres, whereas for large spheres there is a term that goes as the log of the
sphere radius. For large masses, we find evidence for a universal contribution
logarithmic in the mass. In all cases the entanglement entropy is smooth as the
sphere radius crosses the horizon.
