Off - shell Crosscap State and Orientifold Planes
We show that a non-trivial dilaton condensation alters the dimensions of orientifold planes. An off-shell crosscap state which naturally interpolates between the usual onshell crosscap states and their T-duals plays an important role in the analysis. We present an explicit representation of the off-shell crosscap state on an RP 2 worldsheet in the gauge in which the worldsheet curvature in the ...
متن کاملAn Orientifold from F Theory
The massless spectrum of an orientifold of the IIB string theory is computed and shown to be identical to F theory on the Calabi-Yau threefold with h11 = 51 and h21 = 3. Target space duality is also considered in this model.
متن کاملType IIA Orientifold Limit of M-Theory on Compact Joyce 8-Manifold of Spin(7)-Holonomy
We show that M-theory compactified on a compact Joyce 8-manifold of Spin(7)holonomy, which yields an effective theory in D = 3 with N = 1 supersymmetry, admits at some special points in it moduli space a description in terms of type IIA theory on an orientifold of compact Joyce 7-manifold of G2-holonomy. We find the evidence in favour of this duality by computing the massless spectra on both M-...
متن کاملVacua, Connnement and the Continuum Limit
We investigate the dependence of the CP 3 model and of the SU(2) Yang-Mills theory on the vacuum angle. The CP 3 model exhibits a rst order deconnning phase transition in. The critical value of runs from in the strong coupling limit towards zero as is taken to innnity. Qualitatively the same behavior is found in the SU(2) Yang-Mills theory in four dimensions. We discuss the renormalization grou...
متن کاملPlanar Limit of Orientifold Field Theories and Emergent Center Symmetry
We consider orientifold field theories (i.e. SU(N) Yang–Mills theories with fermions in the two-index symmetric or antisymmetric representations) on R3 × S1 where the compact dimension can be either temporal or spatial. These theories are planar equivalent to supersymmetric Yang–Mills. The latter has ZN center symmetry. The famous Polyakov criterion establishing confinement-deconfinement phase ...
