/ 9711039 Strings from Orientifolds
We construct models in 1+1 dimensions with chiral (0, N) supersymmetry by taking orientifolds of type IIB on an eight-torus identified by different numbers of reflections. The resulting models have Dirichlet strings, fivebranes and ninebranes stretched along different directions. The cases we study in detail have residual chiral supersymmetry (0, 8), (0, 4) and (0, 2). The gravitational anomaly...

متن کاملF Theory Orientifolds, M Theory Orientifolds, and Twisted Strings
Orientifolds of the type IIB superstring that descend from F theory and M theory orbifolds are studied perturbatively. One finds strong evidence that a previously ignored twisted open string is required in these models. An attempt is made to interpret the J type torsion in F theory where one finds a realization of Gimon and Johnson’s models which does not require these twisted strings. S-dualit...
متن کاملOn the Complementarity of F-theory, Orientifolds, and Heterotic Strings
We study F-theory duals of six dimensional heterotic vacua in extreme regions of moduli space where the heterotic string is very strongly coupled. We demonstrate how to use orientifold limits of these F-theory duals to regain a perturbative string description. As an example, we reproduce the spectrum of a T /ZZ4 orientifold as an F-theory vacuum with a singular K3 fibration. We relate this vacu...
متن کاملTachyon-free Orientifolds of Type 0B Strings in Various Dimensions
We construct non-tachyonic, non-supersymmetric orientifolds of type 0B strings in ten, six and four space-time dimensions. Typically, these models have unitary gauge groups with charged massless fermionic and bosonic matter fields. However, generically there remains an uncancelled dilaton tadpole.
