We construct type IIA orientifolds on T6/2 × 2 which admit non factorisable lattices. We describe a method to deal with this kind of configurations and discuss how the compactification lattice affects the tadpole cancellation conditions. Moreover, we include D6-branes which are not parallel to O6-planes. These branes can give rise to chiral spectra in four dimensions, thus uncovering a new corner in the landscape of intersecting D-brane model constructions. We demonstrate the construction at an…

Type IIA orientifolds and orbifolds on non-factorizable tori

Oddness from rigidness

We revisit the problem of constructing type IIA orientifolds on T6/2 × 2 which admit (non)-factorisable lattices. More concretely, we consider a 2 × 2' orientifold with discrete torsion, where…

Comments on orientifolds without vector structure

We revisit type I compactifications with a Spin(32)/Z2 gauge bundle that admits no vector structure. We elucidate the relation of this Z2 obstruction to discrete B- field flux and to 't Hooft flux…

Yukawa couplings for intersecting D-branes on non-factorisable tori

A bstractWe compute Yukawa couplings in type IIa string theory compactified on a sixtorus in the presence of intersecting D6-branes. The six-torus is generated by an SO(12) root lattice. Yukawa…

Yukawa couplings from magnetized D-brane models on non-factorisable tori

A bstractWe compute Yukawa couplings in type IIB string theory compactified on a non factorisable six-torus in the presence of D9 branes and fluxes. The setting studied in detail, is obtained by…

Three-family GUT models from heterotic orbifold on E_6 root lattice

We construct three-family supersymmetric GUT models from heterotic string. We investigate compactifications on non-factorizable torus defined by E_6 root lattice, which admits automorphism of Z_3 x…

Towards geometric D6-brane model building on non-factorisable toroidal ℤ4-orbifolds

A bstractWe present a geometric approach to D-brane model building on the non-factorisable torus backgrounds of T6/ℤ4, which are A3 × A3 and A3 × A1 × B2. Based on the counting of ‘short’…

Millions of standard models on 6 '?

: Using previous results on the statistics of intersecting D6-brane models on T 6 / Z ′ 6 we analyse solutions that resemble the gauge group and matter content of the supersymmetric standard model.…

Kähler metrics and gauge kinetic functions for intersecting D6‐branes on toroidal orbifolds – The complete perturbative story

We systematically derive the perturbatively exact holomorphic gauge kinetic function, the open string Kähler metrics and closed string Kähler potential on intersecting D6‐branes by matching open…

Supersymmetric Intersecting Branes on the Type IIA T6/Bbb Z4 Orientifold

We study supersymmetric intersecting D6-branes wrapping 3-cycles in the type-IIA T6/4 orientifold background. As a new feature, the 3-cycles in this orbifold space arise both from the untwisted and…

Type-IIA orientifolds on general supersymmetric ℤN orbifolds

We construct type-IIA orientifolds for general supersymmetric N orbifolds. In particular, we provide the methods to deal with the non-factorisable six-dimensional tori for the cases 7, 8, '8, 12 and…

Z(2)x Z(2)heterotic orbifold models of non factorisable six dimensional toroidal manifolds

We discuss heterotic strings on 2 × 2 orbifolds of non factorisable six-tori. Although the number of fixed tori is reduced as compared to the factorisable case, Wilson lines are still needed for the…

Consistency conditions for orientifolds and D-manifolds.

It is argued that the {ital K}3 orbifold with spin connection embedded in gauge connection corresponds to an interacting conformal field theory in the type I theory.

CHIRAL N=1 4D ORIENTIFOLDS WITH D-BRANES AT ANGLES

D6-branes intersecting at angles allow for phenomenologically appealing constructions of four-dimensional string theory vacua. While it is straightforward to obtain non-supersymmetric realizations of…

Orientifolds with branes at angles

We present supersymmetry breaking four-dimensional orientifolds of type-IIA strings. The compact space is a torus times a four-dimensional orbifold. The orientifold group reflects one direction in…
