Wald's gravitational entropy for ghost-free, infinite derivative
  theories of Gravity
  In this paper, we demonstrate that the Wald's entropy for any spherically
symmetric blackhole within an infinite derivative theory of gravity is
determined solely by the area law. Thus, the infrared behaviour of gravity is
captured by the Einstein-Hilbert term, provided that the massless graviton
remains the only propagating degree of freedom in the spacetime.
