Infinite number of MSSMs from heterotic line bundles?
Stefan Groot Nibbelink, Orestis Loukas, Fabian Ruehle +1
We consider heterotic E8xE8 supergravity compactified on smooth Calabi-Yau manifolds with line bundle gauge backgrounds. Infinite sets of models that satisfy the Bianchi identities…
Anomaly-safe discrete groups
Mu-Chun Chen, Maximilian Fallbacher, Michael Ratz +2
We show that there is a class of finite groups, the so-called perfect groups, which cannot exhibit anomalies. This implies that all non-Abelian finite simple groups are anomaly-fre…
Singlet extensions of the MSSM with Z_4^R symmetry
Michael Ratz, Patrick K. S. Vaudrevange
We discuss singlet extensions of the MSSM with symmetry. We show that holomorphic zeros can avoid a potentially large coefficient of the term linear in the singlet. The eme…
