We present the conformal windows of SU(N) supersymmetric andnonsupersymmetric gauge theories with vector-like matter transforming accordingto higher irreducible representations of the gauge group. We determine thefraction of asymptotically free theories expected to develop an infrared fixedpoint and find that it does not depend on the specific choice of therepresentation. This result is exact in supersymmetric theories while it is anapproximate one in the nonsupersymmetric case. The analysis allows us to sizethe unparticle world related to the existence of underlying gauge theoriesdeveloping an infrared stable fixed point. We find that exactly 50 % of theasymptotically free theories can develop an infrared fixed point while for thenonsupersymmetric theories it is circa 25 %. When considering multiplerepresentations, only for the nonsupersymmetric case, the conformal regionsquickly dominate over the nonconformal ones. For four representations, 70 % ofthe asymptotically free space is filled by the conformal region.  According to our theoretical landscape survey the unparticle physics worldoccupies a sizable amount of the particle world, at least in theory space, andbefore mixing it (at the operator level) with the nonconformal one.
