Permutation orbifolds of heterotic Gepner models
M. Maio, A. N. Schellekens
We study orbifolds by permutations of two identical N=2 minimal models within the Gepner construction of four dimensional heterotic strings. This is done using the new N=2 supersym…
Asymmetric Gepner Models III. B-L Lifting
B. Gato-Rivera, A. N. Schellekens
In the same spirit as heterotic weight lifting, B-L lifting is a way of replacing the superfluous and ubiquitous U(1)_{B-L} with something else with the same modular properties, bu…
Permutation Orbifold of N=2 Supersymmetric Minimal Models
M. Maio, A. N. Schellekens
In this paper we apply the previously derived formalism of permutation orbifold conformal field theories to N=2 supersymmetric minimal models. By interchanging extensions and permu…
SU(5) D-brane realizations, Yukawa couplings and proton stability
Pascal Anastasopoulos, George K. Leontaris, Robert Richter +1
We discuss SU(5) Grand Unified Theories in the context of orientifold compactifications. Specifically, we investigate two and three D-brane stack realizations of the Georgi-Glashow…
Non-supersymmetric Orientifolds of Gepner Models
B. Gato-Rivera, A. N. Schellekens
Starting from a previously collected set of tachyon-free closed strings, we search for N=2 minimal model orientifold spectra which contain the standard model and are free of tachyo…
Non-supersymmetric Tachyon-free Type-II and Type-I Closed Strings from RCFT
B. Gato-Rivera, A. N. Schellekens
We consider non-supersymmetric four-dimensional closed string theories constructed out of tensor products of N=2 minimal models. Generically such theories have closed string tachyo…
