“…Thus the derivative in eq. (4.16) reduces to Starting from the expression for χ N S + l,m , given in [52], one can derive the expression for W ℓ m = χ R − l,m by a shift of the argument z → z + (τ + 1)/2…”

“…The simplest non trivial case is a Type I model on the Quintic [87,88,52]. It is based on the diagonal modular invariant that puts fewer tadpole constraints than the charge conjugation modular invariant.…”

“…As it was argued in [51], these correspond to twisted representations of the underlying N = 2 superconformal algebra (SCA). We will not explicitly consider the interesting possibility of constructing models with large extra dimensions based on (freely acting) orbifolds of K3 × T 2 at Gepner points for K3 [52]. Neither we will consider turning on closed string fluxes (metric torsion, NS-NS 3-form flux and R-R fluxes) and their effect of non-trivial warping of the geometry [104].…”

We derive general formulae for tree level gauge couplings and their oneloop thresholds in Type I models based on genuinely interacting internal N = 2 SCFT's, such as Gepner models. We illustrate our procedure in the simple yet non-trivial instance of the Quintic. We briefly address the phenomenologically more relevant issue of determining the Weinberg angle in this class of models. Finally we initiate the study of the correspondence between 'magnetized' or 'coisotropic' D-branes in Gepner models and twisted representations of the underlying N = 2 SCA.

“…Moreover, we will briefly discuss some phenomenological aspects of such D-brane models. 4 Besides orbifold constructions, semi-realistic models based on non-geometric conformal field theory, such as orientifolds of Gepner models [45,46], have most recently been considered in [47][48][49][50][51][52][53][54]. These vacua are known to describe special points in the moduli space of certain Calabi-Yau manifolds, and the results in the literature indicate that supersymmetric semirealistic chiral particle spectra can be obtained in many of these models [54].…”

Most intersecting D-brane vacua in the literature contain additional massless adjoint fields in their low energy spectrum. The existence of these additional fields make it difficult to obtain negative beta functions and, eventually, asymptotic freedom. We address this important issue for N = 1 intersecting D-brane models, rephrasing the problems in terms of (open string) moduli stabilization. In particular, we consider a Z 2 × Z 2 orientifold construction where D6-branes wrap rigid 3-cycles and such extra adjoint fields do not arise. We derive the model building rules and consistency conditions for intersecting branes in this background, and provide N = 1 chiral vacua free of adjoint fields. More precisely, we construct a Pati-Salam-like model whose SU (4) gauge group is asymptotically free. We also comment on the application of these results for obtaining gaugino condensation in chiral D-brane models. Finally, we embed our constructions in the framework of flux compactification, and construct new classes of N = 1 and N = 0 chiral flux vacua. † Permanent address

“…After some earlier attempts [24], there was quite a revival of interest in the construction of Gepner model orientifolds during the last year [25,26,27,28]. Since Gepner models are known to describe exactly solvable non-linear sigma models on certain Calabi-Yau manifolds at radii of string scale size, the study of such models tells us something about a regime which is not accessible via perturbative supergravity methods.…”
