The Heterotic Road to the MSSM with R parity
Oleg Lebedev, Hans Peter Nilles, Stuart Raby +4
In a previous paper, referred to as a "Mini-Landscape" search, we explored a "fertile patch" of the heterotic landscape based on a Z6-II orbifold with SO(10) and E6 local GUT struc…
Gauged Discrete Symmetries and Proton Stability
Rabindra N. Mohapatra, Michael Ratz
We discuss the results of a search for anomaly free Abelian Z_N discrete symmetries that lead to automatic R-parity conservation and prevents dangerous higher-dimensional proton de…
Seesaw Neutrinos from the Heterotic String
Wilfried Buchmuller, Koichi Hamaguchi, Oleg Lebedev +2
We study the possibility of realizing the neutrino seesaw mechanism in the E8XE8 heterotic string. In particular, we consider its Z_6 orbifold compactifications leading to the supe…
