Ungravity realization in fractional extra dimensions

Abstract

Ungravity by tensor unparticles is realized in AdS(4+N) space through deconstruction. It is shown that ungravity is equivalent to the gravity in extra dimensions. There is a close relation between the scaling dimension of the unparticle operator and the number of extra dimensions. Consequently it is possible to discover the fractional extra dimentions, which would be a stringent signal for unparticles.
