The authors' main claim We construct open descendants of Gepner models, concentrating mainly on the six-dimensional case, where they give type I vacua with rich patterns of Chan-Paton symmetry breaking and various numbers of tensor multiplets, including zero.

We construct open descendants of Gepner models, concentrating mainly on the six-dimensional case, where they give type I vacua with rich patterns of Chan-Paton symmetry breaking and various numbers of tensor multiplets, including zero. We also relate the models in $D < 10$ without open sectors, recently found by other authors, to the generalized Klein-bottle projections allowed by the crosscap constraint.

To study the dependence of $$ on the RR moduli, we use type I/heterotic duality [ref] , which maps the RR two-form to the antisymmetric tensor.

In the following, we will focus on the orientifold projection of the Gepner model with $81$ characters worked out in [ref] , comprising ten hyper multiplets in the antisymmetric representation of the Chan-Paton gauge group $SO(8)$ from the open-string sector and twenty-one neutral hyper multiplets from the closed-string sector.

With respect to many models of the kind [ref] this Type I model is peculiar in that it has only one tensor multiplet, whose scalar component determines the volume of $T^4/_2$, that can be related via Type I / Heterotic duality to the unique tensor multiplet, containing the dilaton in the heterotic side [Additional tensor multiplets can be contributed by heterotic M5-branes, pointlike $E(8)$ instantons, which do not admit a fullfledged worldsheet description.
