Title: Exploring the Dynamics of Orientifold QCD

Abstract: Combining Seiberg duality in N=1 SQCD with planar equivalence between SQCD and a non-supersymmetric QCD-like orientifold daughter (OQCD) we argue for a non-supersymmetric Seiberg duality. We make a precise proposal for this duality beyond the planar limit and consider its implications for the strongly coupled IR dynamics of OQCD - for example, we get the exact range of the conformal window. Supporting evidence for this picture arises from string theory, where Seiberg duality can be motivated with an exact tree-level analysis as a statement about D-brane monodromies in a non-critical string theory
