Within the context of the duality between higher spin gravitational theories and a semi-classical limit of W N minimal models, we consider 2D CFTs with W symmetry at finite temperature, deformed by the presence of a chemical potential for the spin–three current. As a perturbative expansion in the chemical potential, we compute the R ́enyi and entanglement entropies for a single interval. The leading correction is universal and matches the holographic result, based on Wilson line functionals, for higher spin black holes dual to CFTs with W symmetries.
