Higher-dimensional black holes with a conformally invariant Maxwell source [PDF]
, 2007 We consider an action for an abelian gauge field for which the density is given by a power of the Maxwell Lagrangian. In d spacetime dimensions this action is shown to enjoy the conformal invariance if the power is chosen as d/4.
