DESCRIPTION:There has been phenomenal recent progress in computing CFT\nen
 tanglement and Renyi entropies\, holographically and otherwise. We extend\
 n these investigations to the higher spin regime -- where sensible notions
  of\ngeometry are sorely lacking -- by computing ground state Renyi entrop
 y in\ncertain classes of holographic CFTs with higher spin symmetry. Our\n
 calculations are performed at both classical and one-loop level\, from\ngr
 avity and CFT. Along the way\, we establish perturbative methods for\ncomp
 uting Renyi entropy in any CFT\, with or without higher spin symmetry and\
 nin various spacetime dimensions.
