  • D6-brane splitting on type IIA orientifolds
    Cvetič, Mirjam ...
    We address both the string and field theory aspects of D6-brane splitting on Type IIA orientifolds with supersymmetric intersecting D6-branes. We focus specifically on the Z_2 x Z_2 orientifolds and ... address the symmetry breaking pattern for D6-branes parallel with the orientifold 6-planes as well as those positioned at angles. We demonstrate that the string theory results, which have a beautiful geometric interpretation, are in one to one correspondence with the field theory results associated with vacuum expectation values (Higgsing) of moduli in the antisymmetric representation of Sp(2N) gauge symmetry (for branes parallel with orientifold planes) or adjoint representation of U(N) (for branes at general angles). In particular, moving branes away from the orientifold planes results in change of the chiral spectrum and may change the number of families. We also provide the first new examples of the supersymmetric Standard-like models with the electroweak symmetry arising from the branes parallel with the orientifold planes; one four-family example of that type is free of chiral Standard Model exotics.
